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...
