Question

A machine uses an effort of 25n to lift a load of 625n. calculate the velocity ratio if it has an efficiency of 25%​

Answer 1

Answer:

Load raised by the machine, (L) = 25 N

Given, the mechanical advantage of the machine, M.A. = 5.

Effort, (E) = ?

M.A. = 25E=5

∴ Effort = 5 N

Explanation:

Load raised by the machine, (L) = 25 N

Given, the mechanical advantage of the machine, M.A. = 5.

Effort, (E) = ?

M.A. = 25E=5

∴ Effort = 5 N
