Three monkeys A, B and C with masses of 10, 15 & 8 Kg respectively are climbing up & down the rope suspended from D. At the instant represented, A is descending the rope with an acceleration of 2 m/s2 & C is pulling himself up with an acceleration of 1.5 m/s2. Monkeys B is climbing up with a constant speed of 0.8 m/s .Treat the rope and monkeys as a complete system & calculate the tension T in the rope at D.( `g = 10 m/s^2` )
