A steel dia 10 mm passes through a brass tube of internal dia 15mm and external dia is 25 mm. The bolt is tightened by a nut. The length of tube is reduced by 1.5mm and the length of tube is 1500mm. if temp. of assembly is raised by 40o . Find the axial stress in bolt and tube before and after heating. Provided that :
Es = 2 x 105 N/mm2
Eb = 1 x 105 N/mm2
s = 1.2 x 10-5 N/oC
b = 1.9 x 10-5 N/oC
(b) A prismatic bar of cross-sectional area A is subjected to axial force ‘P' at C. Determine the reactions at supported and deflection at C.
the velocity of a particle moving along x axis is defined by v=kx^3-4x^2+6x where v is in m/s,x in m and k is a constant .if k=2 compute the acceleration when x=2m
