Unformatted text preview: ME 2” Salim 5 *8-16. Two designs for a shock support are shown in the figure. The Spring has a stiffness of k = 15 kN/m and in (a) it is uncompressed, whereas in (b) it is originally stretched 0.2 m. Determine the average normal stress in the 5-mm-diameter bolt shank at A when the 6-kN load is applied. In (b) the bracket B is not connected to the support. 0’56 ‘1’)" 1% 61w .3 a “’"l/ $1"ch F’kx; 6k/V=Url¢/t/h) x K: MW 2 0.2:“. WW é"! '3 614‘th mflnréd [J 0’:- i :.
