ASVAB Mechanical Comprehension Force ️Ans - Any influence that causes an object to undergo a change in speed, a change in direction, or a change in shape. (a push or pull) Velocity ️Ans - Speed in a given direction Acceleration ️Ans - A change in velocity; the rate of change of velocity with time. Force = Mass x Acceleration ️Ans - Mathematical formula to determine Force For every action (force) in nature, there is an equal (in size) and oppo...

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 s...
