ASVAB Mechanical Comprehension

ASVAB Mechanical Comprehension How much force is needed to lift the 10Kg weight? ️Ans - 5 Kg In a double-pulley system, the force is equal to the weight divided by two. It will require a 5 Kg force to lift a 10Kg weight. The smaller gear has 8 teeth, and the larger gear has 16 teeth. When the larger gear makes 12 revolutions, how many revolutions will the smaller gear make? ️Ans - 24 The gear ratio here is 2:1, meaning that for every revolution of the larger gear, the smaller gear revolves twice. If the larger gear revolves 12 times, the smaller gear will revolve twice as many times. Which of the following is the basis for Pascal's Law? ️Ans - The amplification of force in a hydraulic system. The third principle of hydraulics is the basis for Pascal's Law and states that when pressure is applied to a fluid, the pressure is transmitted evenly throughout An 80-lb child is sitting on one end of a seesaw. If another 80-lb child jumps from a high platform onto the other end of the seesaw, what will happen? ️Ans - The first child will be lifted into the air, but remain seated. The force of the second child landing on the seesaw will propel the other end of the seesaw into the air. What is a vector quantity? ️Ans - Gravity Gravity is a type of force, and since force has magnitude and direction it is known as a vector quantity. Which of the following describes the relationship between kinetic energy, mass, and velocity? ️Ans - 2(KE) = mv^2 One horsepower is equivalent to ️Ans - 746 watts Horsepower is a unit used to rate internal combustion engines.
