Question

08.4 A large box 5.0 m on a side has mass 100 kg. A force F is applied as shown, making an angle ? = 30o with respect to the vertical. The coefficient of static friction between the box and the floor is 0.30. What range of values for the force F will tip the box over without having the box slide?

Explanation / Answer

Normal force,N=mg cos (theta)=100*9.8*cos30=848.70 N

The static friction force,Fs needed such that the block will move is, Fs=coeffecient friction*N

Fs=0.3*848.70=254.61 N

So an applied force of 255 N makes the box moves
