A 2 cm by 2 cm by 2 cm rubber engine mount (E = 30 MPa, Poisson ratio = 0.4999) must support a 300 kg motor. What (maximum) deflection (in cm) will occur for a.) vertical and b.) horizontal mountings. Assume the weight is uniformly distributed across a face of of the material. Note, in the vertical mount the motor sits atop the mount, while in the horizontal geometry the motor is mounted on the side of the mount, which is supported on the opposite side. c) Is the engine mount properly designed for horizontal mounting? Explain briefly why.
