3. You have an adjustable, wooden incline and want to know how large of an angle would you need to raise the incline before several objects will slide down the incline. Determine the angles where the following object will begin to slide down the incline: ice (µ = 0.05), wood (µ = 0.25), steel (µ=0.4), and a brick (µ = 0.6). (2.9°, 14.0°, 21.8°, 31.0°)

Expert Solution

There are four tables, for each angle frictional force(fr) and downward force parallel to plane (F= mgSin(theta)) has been calculated and comparison of both values.

In fourth table we are getting F > fr in all cases it means at an angle theta = 31° , all types of block slide down easily.
