QUESTION #54 Longitudinal Strain on Moving Wires
Each of three blocks P, Q and R shown in figure has a mass of 3 mathrm~kg. Each of the wire A and B has cross-sectional area 0.005 mathrm~cm^2 and Young's modulus 2 times 10^11 mathrmNm^-2. Neglecting friction, the longitudinal strain on wire B is \_ \_ \_ \_ times 10^-4. (Take g = 10 mathrmm / s^2) {{IMG1}}
