The normal force exerted by the pins at points A and B .

Question

A uniform plank 6.0 m long rests on two supports,2.5 m apart (Fig.P12.44).The gravitational force on the plank is 100 N.The left end of the plank is 1.5 m to the left of the left support,so the plank is not centered on the supports.A persom is standing on the plank half a meter to the right of the right support.The gravitational force on this person is 80.0 N.How far to right can the person walk before the plank begins to tip?

When you bend over, a series of large muscles, the erector spinae, pull on your spine to hold you up. The following figure shows a simplified model of the spine as a rod of length L that pivots at its lower end. In this model, the center of gravity of the 270 N270 N weight of the upper torso is at the center of the spine. The 140 N140 N weight of the head and arms acts at the top of the spine. The erector spinae muscles are modeled as a single muscle that acts at a 1212-degree angle to the spine. Suppose the person in the figure bends over to an angle of 3030 degrees from horizontal. The center of gravity is half the length, and the center of gravity for the upper torso is 2/32/3 of the length A. What is the tension in the erector muscle? B. A force from the pelvic girdle acts on the base of the spine. What is the component of this force in the direction parallel to the spine? This large force is the cause of many back injuries.

Two wires of unknown compositions, same length, and same diameter were made to support a rod, which supports another heavy weight w. As w was moved farther from A but closer to B, it snapped out. Which of the following is a true statement? A B O B has lesser Young's modulus than A. A and B have the same Young's modulus. A has lesser Young's modulus than B. None of the given choices.
