The correct answer is I, II, III (B). Return to Top of Page Sample Questions from the General Structures Sample Question 1 A handrail 42 inches in height has vertical supports at 4 feet on center. If a force of 50 lbs./ lin. Ft. is applied to the handrail, what is the moment at the bottom of the vertical support? A. 200 in. lbs. B. 4,200 in. lbs. C. 8,400 in. lbs. D. 12,600 in. lbs. Answer with Narrative A moment is a force times a distance. With a force of 50 lbs. / linear foot, applied over 4 linear feet, the force will be equal to 50 lbs. / lin. Foot X 4 lin. Feet = 200 pounds. The moment will be (200 lbs.)(42 in.) = 8,400 in. lbs. (Answer C). Sample Question 2 A simple beam 15 feet in length is subjected to a uniformly distributed load of 2,000 lbs. The value of the maximum vertical shear is: A. 1,000 lbs B. 2,000 lbs C. 4,000 lbs D. Unable to determine from given information Answer with Narrative When a simple beam 15 feet in length is subjected to a uniformly distributed load of 2,000 lbs, the value of the maximum vertical shear is 1,000 lbs (Answer A). With this condition, the value for both reactions would be 1,000 lbs. Constructing a shear diagram would indicate that the maximum vertical shear would be 1,000 lbs. Return to Top of Page Sample Questions from the Lateral Forces Sample Question 1 A loss of soil bearing strength (for a building) as a result of a sudden rush of water to the surface of the earth is termed: A. Drift B. Soft story C. Torsional rotation D. None of the above Answer with Narrative A loss of soil bearing strength (for a building) as a result of sudden rush of water to the surface of the earth is termed Liquefaction. None of the above (answer D) is the correct answer. Drift (A) is the horizontal displacement of a building element due to a lateral force. Soft story (B) is the relative lack of stiffness of one story of a building relative to an adjacent story. Torsional rotation (C) is the rotation of a building in plan as a result of unsymmetrically located shear-resisting elements. Sample Question 2 In a 5-story building the earthquake shear force at the roof line is ____________ the force at the forth story. A. More than B. Less than C. Equal to D. None of the above Answer with Narrative In a multi-story building the force near the top (roof) will be Less Than (answer B) the force at any level below the level in question. The earthquake force is directly related to the weight of the structure and the weight of the structure at, or near, the roof will be less than the cumulative weight below it. Return to Top of Page Sample Questions from the Materials and Methods Sample Question 1 A measure utilized to determine the rapidity with which fire will spread across the surface of a material is termed: A. Fire resistance B. First stop C. Flame spread rating D. None of the above Answer with Narrative A measure utilized to determine the rapidity with which fire will spread across the surface of a material is termed the Flame spread rating (C). Fire resistance (A) is a characteristic of a material to resist fire. Firs stop (B) is an element inserted into a space to retard the spread of fire through the space. Sample Question 2 What type of cement would be appropriate to use when soil conditions indicate a high-sulfate content: A. Type II B. Type III C. Type IV D. Type V Answer with Narrative The type of cement to use when soil conditions indicate a high-sulfate content is type V (D). Type II (A) is used when conditions indicate moderate heat or moderate sulfate. Type III (B) is a high-early cement, used when the 28-day waiting period for the concrete to reach its design strength is to be reduced. Type IV (C) is a low-heat cement, used when pouring large volumes of concrete as in a dam or a mat flooring. Return to Top of Page Sample Questions from the Mechanical, Electrical, Plumbing and Acoustical Sample Question 1 The latent heat of fusion is: A. The specific amount of heat required to melt a solid creating a liquid B. The specific amount of heat required to change a liquid into a gas C. Enthalpy D. None of the above Answer with Narrative The latent heat of fusion is the specific amount of heat required to melt a solid, creating a liquid (answer A). The specific amount of heat required to change a liquid into a gas (B) is the latent heat of evaporation. Enthalpy (C) is the sum of sensible and latent heat. Sample Question 2 How many B.T.U./hr. flows through each square foot of wall if the R value is 12.5 with a temperature difference of 20-degrees between the two sides of the wall? A. 1.2 B. 1.6 C. 10.3 D. 14.5 Answer with Narrative 1.6 BTUs/hr (answer B) flows through each square foot of wall, the R value of which is a temperature difference of 20-degrees between the two sides of the wall. An R value can be thought of as the number of hours required for 1 BTU to penetrate one square foot of a material for each degree of temperature difference between the two sides of the material. The overall coefficient of heat transfer is the reciprocal of R, called the U value. With an R value of 12.5, the U value = 1/12.5 = 0.08. The amount of BTUs that would flow through this wall would be (0.08.)(20-degrees) = 1.6 BTU/hr (answer B). Based upon this calculation, all of the other selections are incorrect. Return to Top of Page Sample Questions from the Pre-Design Sample Question 1 A building lot of 200 ft. x 200 ft. is to have a finish elevation of 100.0'. The existing elevation at the four corners is 102.0', 104.0', 106.0', and 108.0'. The amount of cut will be approximately: A. 3,800 cu. yd. B. 7,400 cu. yd. C. 12,500 cu. yd. D. 40,000 cu. yd. Answer with Narrative A building lot of 200 ft. x 200 ft. is to have a finish elevation of 100.0'. The existing elevation at the four corners is 102.0', 104.0', 106.0', and 108.0'. The amount of cut for the described site will be approximately 7,400 cu. yd. (answer B). The soil to be cut would be the difference between 100.0' and the average of the soil height existing. This would be 2' + 4' + 6' + 8', divided by 4 = 5'. The cubic feet of cut would be 200' x 200' x 5' = 200,000 cubic feet. The selections are noted in cubic yards so that 200,000 cubic feet/27 cubic feet = 7,400 cubic yards (answer B). All other selections are incorrect. Sample Question 2 The landscape architect for the Columbia Exposition of 1893 was: A. Clarence Stein B. Simon Eisner C. Frederick Law Olmstead D. Frank Lloyd Wright Answer with Narrative The landscape architect for the Columbia Exposition of 1893 was Frederick Law Olmstead (answer C). Clarence Stein (A) and Simon Eisner (B) have been involved in 20th Century planning. Frank Lloyd Wright (D) was not a landscape architect. A question such as this might be answered by a process of elimination if a little bit is known about several of the noted individuals.
