1. When the load line coincides with the centroid of the rivet group, the rivets are subjected to
(a) shear only
(b) tension only
(c) bending only
(d) shear as well as tension
Ans- (a)
2. An ISMB 500 is used as a beam in a multistory construction. From the viewpoint of structural design, it can be considered to be ‘laterally restrained’ when
(a) the tension flange is laterally restrained
(b) the compression flange is laterally restrained
(c) the web is adequately stiffened
(d) the conditions in both (a) and (c) are met.
Ans- (b)
3. Deflection limitations over beams are imposed because excessive deflection may cause
(a) undesirable twisting and distortion of end connections
(b) problems in drainage system
(c) psychological effect on users
(d) All of the above
Ans- (d)
4. Purlins are to be chosen for a roof truss of 20 m spam, 4 m rise. Trusses are spaced at 4.5 m centre-to-centre. A most efficient design results from the use of
(a) angle sections
(b) channel sections
(c) circular hollow sections
(d) square hollow sections
Ans- (b)
5. How is water stored in an aquifer?
(a). in an open underground lake
(b). in cracks and spaces in rocks
(c). in impermeable rock
(d). in wells and springs
Ans-(b)
6. How do droplets become heavy enough so that the droplets fall as rain or snow?
(a). The droplets gain mass from condensation within the clouds.
(b). When evaporation occurs, extra water vapors forms into more droplets.
(c). The droplets bump together and form larger droplets.
(d). The hotter air allows the droplets to solidify and fall from the clouds.
Ans-(c)
7. What causes water to rise out of the ground in hot springs?
(a). Earth’s core heats the water, making the hotter water less dense.
(b). A pump is used to bring water to Earth’s surface.
(C. Gravity pulls water down through permeable materials.
(d). A nearby volcano heats the water, making the hotter water less dense
Ans-(d)
8. Mercury is a hazardous chemical. Which item does not contain mercury?
(a) Computer disks
(b) Blinking lights in sneakers
(c) Fluorescent light bulbs
(d) Thermometers
Ans-(a)
9. Which items are recyclable?
(a) Plastic milk jugs
(b) Cereal boxes
(c) Aluminum soda cans
(d) All of the above
Ans-(d)
10. How long does it take Styrofoam to break down in a landfill?
(a) 10 Years
(b) 50 Years
(c) 100 Years
(d) 500 Years
Ans-(d)
