Question

a worker pushes a load up a gentle ramp. the incline has an ideal mechanical advantage of 10. find the length of the ramp. length = unit 8 ft

Explanation:

Step1: Recall the formula for IMA of an inclined plane

The ideal mechanical advantage (IMA) of an inclined plane is given by the formula \( IMA=\frac{length\ of\ the\ ramp(l)}{height\ of\ the\ ramp(h)} \).

Step2: Identify known values

We know that \( IMA = 10 \) and \( h=8\ ft \). We need to find \( l \).

Step3: Rearrange the formula to solve for \( l \)

From \( IMA=\frac{l}{h} \), we can rearrange it to \( l = IMA\times h \).

Step4: Substitute the known values

Substitute \( IMA = 10 \) and \( h = 8\ ft \) into the formula: \( l=10\times8 = 80\ ft \).

Answer:

80
