Question

A ramp with a mechanical advantage of 8 lifts objects to a height of 1.5 meters how long is the ramp

Answer 1

Given data:

M.A. = 8 (No units),

Ramp height (h)= 1.5 m, lifted,

Determine how long is the ramp=?

General formula

Mechanical Advantage = (Ramp length) ÷ (Ramp height),

M.A = l ÷ h

8 × 1.5 = l = 12 m long

length of the ramp l ramp = 12 m
