The two stepped solid cylinders in Figure P4.5 consist of the same material and have an axial force f applied to them. Determine the equivalent translational spring constant for this arrangement. (Hint: Are the two springs in series or in parallel?)
A table with four identical legs supports a vertical force. The solid cylindrical legs are made of metal with E = 2 × 1011N/m2. The legs are 1 m in length and 0.03 m in diameter. Compute the equivalent spring constant due to the legs, assuming the table top is rigid.
