In the figure shoen calculate the angle of friction . The block dows not slide. Take `g=10(m)/(s^2)`.

Text Solution

Verified by Experts

The correct Answer is:
`theta=tan ^(-1)((1)/(2))`

`R=mg+60=160N`
`f=80N( :' ` No sliding `)`
angle of friction `theta=tan ^(-1).(f)/(R)=tan^(-1).(80)/(160) theta=tan^(-1).(1)/(2)Ans.`
