hello I need help solving this questions please thank you so much in advance!

0 El 20. The 52.0cm diameter disk rotates counterclockwise on an axle through its center. F1=59.2N, F2=63.9N, F3=63.9N, F4=59.2N, and d=6.58cm. What is the net torque about the axle? Let the counterclockwise direction be positive. y F3 F2 Submit Answer Tries 0/10 ,0 El 12. Force F=(-18.4i + 12.7j) N is exerted on a particle at r=6.45j rn. What is the magnitude of the torque on the particle about the origin? Submit Answer Tries 0/10 ,0 E! A 9.18m long rigid beam with a mass of 148.9kg is supported at each end. A 44.2kg student stands 3.78m from support 1. How much upward force does each support exert on the beam? (Enter your answer for support 1 first, followed by your answer for support 2.) Submit Answer Tries 0/10 Supimrt 2 Starting from rest, a 13.6cm diameter compact disk takes 8.185 to reach its operating rotational speed of 2055.0 rpm (revolutions per minute). Assume that the angular acceleration is constant. The disk's moment of inertia is 6.69E-5kg~m2. How much torque is applied to the disk? Submit Answer Tries 0/10 How many revolutions does it make before reaching full speed? (Do not enter a unit.) Submit Answer Tries 0/10
