You are constructing a mobile out of 5 identical toy helicopters, each of mass m = 29.9 g. 4 identical sticks (each length /= 20.6 cm, and negligible mass), and thin string of negligible mass. The distance from the left-hand side of each stick to the attachment point of the sting supporting it are x through x4 respectively, as shown in the diagram. The tensions in the supporting strings are 7; through T4 as shown. You want to design the mobile so that it is in static equilibrium. T 13% Part (a) Find the tension in Newtons in the string T.

Answer rating: 100% (QA)

To solve this problem we can start by analyzing the forces acting on each stick and helicopter Since the mobile is in static equilibrium the net force and net torque acting on each object must be zero ... View the full answer
