.

For each mass, calculate the corresponding shear force, directed along the incline; then compare them.


For the left mass, the shear force is 100*sin(30°) =  = 50.0 pounds.


For the right mass, the shear force is 85*sin(45°) =  = 60.10 pounds.


For the right mass, the shear force is greater; hence, WHAT ?
