1.6-16 A shock mount constructed as shown in the figure is used to support an expensive instrument. The mount consists of an outer steel tube with inside diameter b, a central steel bar of diameter d that supports the load P, and a hollow rubber cylinder(height h) bonded to the tube and bar. (a) Obtain a formula for the shear stress t(타우) in the rubber at a radial distance r from the center of the mount. (b) Obtain a formula for the downward displacement d(델타) of the bar due to the load P, assuming that G is the shear modulus of elasticity of the rubber and that the steel tube and bar are rigid.
