A 25-Kg Television Set Rests on Four Rubber Pads That $2.6 \times 10 ^ { 6 } \mathrm {~Pa}$

question 53

Multiple Choice

A 25-kg television set rests on four rubber pads that are on the floor, each one having a height of 1.0 cm and a radius of 0.60 cm. A horizontal force is applied to the television set. When the pads are just at the point of sliding over the floor, how far has the television set moved sideways due to the deformation of the pads? The coefficient of static friction between the rubber and the floor is 1.0 and the shear modulus of these rubber pads is $2.6 \times 10 ^ { 6 } \mathrm {~Pa}$
