What Is Static Equilibrium? Problems 13 are grouped. 1. C A ball is attached to a strong, lightweight rod (Fig. P14.1). The rod is supported by a horizontal pin near the top. The ball is at rest. Is the ball in static equilibrium? If not, why not? If so, which type of equilibrium is itstable, unstable, or neutral? Hint: What would happen if you displaced the ball slightly? FIGURE P14.1
A vertebra is subjected to a shearing force of 500 N. Find the shear deformation, taking the vertebra to be a cylinder 3.00 cm high and 4.00 cm in diameter.
One end of a vertical metallic wire of length 2.0m and diameter 1.0mm is attached to a ceiling, and the other end is attached to a 5.0N weight pan, as shown below. The position of the pointer before the pan is 4.000cm . Different weights are then added to the pan area, and the position of the pointer is recorded in the table shown. Plot stess versus strain for this wire, then the use the resulting curve to determine Young’s modulus and the proportionality limit of the metal. What metal is this most likely to be?
