FCTC MECHANICAL REASONING TEST Questions and Verified Answers 100% Correct Grade A+ 1. A)Post A The weight is distributed more on the side of post A, Therefore, it is holding up the greatest part of the load. Answer: Which post holds up the greater part of the load? A- Post A B- Post B C- Both equal D- Not clear 2. C)Neither of the other gears Because of the way the gears are meshed, both gear 1 and gear 3 will move in the opposite direction of gear 2. 3 / 32 Answer: Which of the other gears is moving in the same direction as gear 2? A) Gear 1 B) Gear 3 C) Neither of the other gears D) Both of the other gears 3. A)A Pulley A is the smallest gear. Therefore, it must turn faster (make more revo-lutions per minute). Answer: In this arrangement of pulleys, which pulley turns fastest? A) A B) B C) C D) D 5. A)21 Since gear A has 15 teeth and gear B has 10 teeth, gear A is 1.5 the size of gear B. Therefore, 14 x 1.5 = 21. 4 / 32 Answer: 1. When gear A makes 14 revolutions, how many revolutions will gear B make? A) 21 B) 17 C) 14 D) 9 6. C)Air pressure on top of the liquid The siphon works, in part, because of air pressure on the top of t he liquid. Answer: In Answer: the illustration above, liquid is being transferred from the barrel to the A) The vacuum at the lower end of the hose B) The difference between the fluid volumes in the barrel and bucket C) Air pressure on top of the liquid D) Capillary action 7. C)Move downward until it reaches the floor Newton's Law of Motion states that a body at rest will stay at rest unless acted on by 5 / 32 an outside force. Conversely, a body in motion stays in motion unless acted on by an are at rest outside force. In this picture, both objects (equilibrium). When an outsidequilibrium force is practically no added to weight 1, the e a pulley, with d as indicated. changes, moving this weight downward. Because the pulley has 1 will friction, the weight strikes the floor. Answer: The figure above represents practically no friction, from which two 10pound weights are suspende If a downward force is applied to weight 1, it is most likely that weight A) Come to rest at the present level of weight 2 B) Move downward until it reaches with weight 2 C) Move downward until it reaches the floor D) Pass weight 2 in its downward motion and then return to its present position 8. B)32 gallons per minute The volume is dependent on the area of the outlet. Since A= rÀ² and r = d/2 , then A= (Àd²/4) where A is the area and d is the diameter.
