2.41. A3-kg block is hanging in equilibrium from a coil spring of diameter 5 cm made from a steel
rod of diameter 5 mm. The shear modulus of the spring's material is G = 80 × 10° N/m?
and the spring has 25 active coils. A weight W is dropped from 20 cm onto the block.
On impact the weight attaches itself to the block. What is the largest weight that can be
dropped such that the spring's elastic shear strength of 100 x 106 N/m2 is not exceeded?
