Question

Do not round intermediate calculations; however, for display purposes report intermediate steps rounded to four significant figures. Give your final answer(s) to four significant figures. The double pendulum shown consists of two particles with masses m1 = 8.5 kg and m2 = 12 kg connected by two inextensible cords of length L1 = 1.5 m and L2 = 3 m and negligible mass. If the system is released from rest when theta = 10 degree and phi = 20 degree. determine the tension in the two cords at the instant of release.

Explanation / Answer

let L1 has tension T1 and L2 has T2 ;
T2=m2*gcos =110.62 N;

T1=(m1g+T1)cos10 =191.06 N
