Question

explain different kinds of levers how mechanical advantage of compound lever is calculated​

Answer 1

$\huge\underline\mathfrak\pink{♡Answer♡}$

In all types of compound lever, the rule is that force multiplied by the force arm equals the weight multiplied by the weight arm. ... With the dimensions shown, the mechanical advantage, W/F can be calculated as 103 × 94 = 7.5, meaning that an applied force of 1 pound (or 1 kg) could lift a weight of 7.5 lb (or 7.5 kg).
