Question: A cylindrical eraser of negligible mass is dragged across a paper at a constant velocity to the right by its pencil. The coefficient of kinetic friction between eraser and paper is 0.640. The pencil pushes down with 3.80N. The height of the eraser is 1.30cmand its diameter is 0.720cm. Its top surface is displaced horizontally 0.930mm relative to the bottom.
Part A: Determine the shear modulus of the eraser material.
Please show all work and steps to find the shear modulus of the eraser material.
