The uniform 19.0 kg beam below is 6.4 m long and is perfectly balanced about a point 1.4 m from the left end. What is the mass of the block? (Hint: when calculating the torque due to the weight of the beam, consider all of its mass to be located at its center of mass.)
Computation A 6-kg bowling ball rests on a uniform beam of length L and mass M, as in the figure. The beam is supported at two points separated by a distance BL where ß = 0.59 and the bowling ball is a distance d from support point 1. Find the largest distance dmax such that the beam does not tip if M = 17 kg and L = 4.9 m. [Note: To keep the bowling ball on the beam, report an answer of dmax ≤ L. For some values, a correct calculation gives dmax > L. That means the bowling ball can be placed anywhere on the beam without tipping and, in that case, the correct answer is dmax = L = 4.9 m.) 2 dmax m L BL- d M Report your numerical answer below, assuming three significant figures.

A person places his hand palm downward on a scale and pushes down on the scale until it reads (8.31x10^1) N. The triceps muscle is responsible for this arm extension force. Find the force (in N) exerted by the triceps muscle. The bottom of the triceps muscle is 2.50 cm to the left of the elbow joint, and the palm is pushing at approximately 35.0 cm to the right of the elbow joint. (please ignore the number 96 shown in the scale). Give your answer with three significant figures.
