Question

pulling force making an angle “@” to the vertical is applied on a block of weight“W' placed
a horizontal table. If the angle of friction is d, the magnitude of the force required move the body is equal to​

Answer 1

Answer:

F required= Fr + ( coeff friction)×W×cos(d).

Explanation:

Normal force= W

Force applied =F cos(@)

Friction=(fric coeff)×W×cos(d).

So,

Fr= F cos(@)-(fric coeff)×W×cos(d).

F cos(@)= Fr + Frictional force.
