Question

A block of mass 20kg is sitting on a surface inclined at 0=45, Detemin the minimum force necessary to prevent Slipping if the coefficient of static friction is 0.5.
​

Answer 1

Answer:

It's too simple dear and boring too...

Your answer is:-

25 \sqrt{2}252

Actually answer comes from making the body on inclined surface in equilibrium....

This is done by equation :-

mgsin(45°) - 0.5mgcos(45°) = F....

Well love you dear....
