Question

ratio of effort arm to load arm is​

Answer 1

Answer:

Velocity ratio (VR) is the ratio of the lengths of out-lever to in-lever (length of resistance arm/effort arm). To increase the velocity ratio that the load is moved, increase the resistance arm by moving the fulcrum closer to the effort. The higher the VR, the greater the speed of the lever.
