what is the advantage of the system of gears shown in the image? a the larger gear can be moved by applying a relatively small force on the smaller gear. b the force applied on the smaller gear is transmitted without any loss to the larger gear. c the direction of motion can be changed without changing the direction of the applied force. d the system would continue to move without any further force, after an initial force has set it in motion.

Answer

Brief Explanations:

Gears are mechanical devices. When a small - sized gear meshes with a large - sized gear, a small force applied on the smaller gear can move the larger gear due to the mechanical advantage provided by the gear ratio. In real - world scenarios, force transmission in gears has some losses (ruling out B), changing the direction of motion usually requires a change in the direction of the applied force in simple gear systems (ruling out C), and a gear system cannot move perpetually without any further force due to friction and other resistive forces (ruling out D).

Answer:

A. The larger gear can be moved by applying a relatively small force on the smaller gear.
