The object shown below (length = 4 m) remains completely stationary, despite the fact that three forces act on it. Forces 1 and 3 act at either end, while force 2 acts 1/4 of the way from the left end. -TIL Co TIL NTIL If the size of force 3 is 4 N, then how large must the other two forces be? F1 = N F2 = N (For excellent practice, see if you can also get these answers using different pivots!)Below is a dlagram of a baseball/forearm system at rest. It is acted on b bicep force, and a force from the upper arm bone (attached at the elbo y four different forces: the weight of the forearm, the welght of the baseball, the w). Use the following values: length of forearm = L = 16 cm elbow to bicep distance = d = 2 cm mass of forearm 2 M : 5 kg mass of baseball = m = 2 kg 3.) Based on torque conSIderations, the force of the bICEp must be greater than Vl the combined weight of the baseball/forearm. (Make sure you understand the reasoning.) b.) How large IS the force exerted by the bicep? l__' N \fTo determine the location of his center of mass, a physics student lies on a lightweight plank supported by two scales L = 4.00 m apart. (a) If the left scale reads 252 N, and the right scale reads 135 N, find the student's mass. kg (b) Find the distance from the student's head to his center of mass. m\fOn the Wheel of Fortune game show, a solid wheel ( of radius 6.6 m and mass 10 kg) is given an initial counterclockwise angular velocity of +1.15 rad/s. It then smoothly slows down and stops after rotating through 3/4 of a turn. (a) Find the frictional torque that acts to stop the wheel. 1 = N . m (b) Assuming that the torque is unchanged, but the mass of the wheel is doubled and its radius is halved. How will this affect the angle through which it rotates before coming to rest? (Make sure you can reason this with proportionalities.) O increase O decrease O stay the same
