A force of 3kgf is just sufficient to pull a block of 5kgf .Find the coefficient of friction and angle of Friction?
Yes, the value of
->31 degrees approx
Coefficient of friction
Here, the pulling force need to be little more than the friction force beneath the block.
The limiting static friction shall be 3 kgf.
The normal thrust is due to the weight of the block itself.
The normal reaction shall be 5 kgf.
Thus, coefficient of friction
Angle of friction
