Mechanical Properties of Solids · Elasticity

A lift of mass 1600 kg is supported by thick iron wire. If the maximum stress which the wire can withstand is 4×108 N/m24\times10^{8}\ \mathrm{N/m^2} and its radius is 4 mm, then maximum acceleration the lift can take is m/s2\mathrm{m/s^2}. (take g=10 m/s2g = 10\ \mathrm{m/s^2} and π=3.14\pi = 3.14)
