Example34The masses m, m2 and m3the three bodies shown in Fig. 3(a).24 are 5, 23 kg respectively. Calculate the values ofTi, T2 and T3 when (i) the whole systemsgoing upward with an acceleration of 2 m/si) the whole system is stationary (g- 98 m/s)fndension |

Answer» when the system is at rest tension= weight of the body=mg so, t1=5*10=50,likewise t2=20 and t3=30(unit=N) when the system is acclerated upwards a pseudo force acts on the body downwards so,tension=mg+ma t1=5*10+5*2=60N,likewise t2=24N and t3=36N |
