Explanation Given information: The yield stress for the material is σ Y = 50 ksi . Calculation: Consider a critical point in the material is subjected to in-plane principal stresses σ 1 = τ and σ 2 = − τ . Apply the maximum shear stress theory for plane stress as shown below. | σ 1 − σ 2 | = σ Y Here, σ 1 and σ 2 are the principal stresses and σ Y is the principal yield stress

Question 1. A tube rotates in the horizontal ry plane with a constant angular velocity w about the z-axis. A particle of mass m is released from a radial distance R when the tube is in the position shown. This problem is based on problem 3.2 in the text. R m 2R Figure 1 x a) Draw a free body diagram of the particle if the tube is frictionless. b) Draw a free body diagram of the particle if the coefficient of friction between the sides of the tube and the particle is = k = p. c) For the case where the tube is frictionless, what is the radial speed at which the particle leaves the tube? d) For the case where there is friction, derive a differential equation that would allow you to solve for the radius of the particle as a function of time. I'm only looking for the differential equation. DO NOT solve it. 1 e) If there is no friction, what is the angle of the tube when the particle exits? • Hint: You may need to solve a differential equation for the last part.

Question 2. A smooth uniform sphere of mass m and radius r is squeezed between two massless levers, each of length 1, which are inclined at an angle with the vertical. A mechanism at pivot point O ensures that the angles & remain the same at all times so that the sphere moves straight upward. This problem is based on Problem 3-1 in the text. P P r Figure 2 a) Draw appropriate freebody diagrams of the system assuming that there is no friction. b) Draw appropriate freebody diagrams of the system assuming that there is a coefficient of friction between the sphere and the right lever of μ. c) If a force P is applied between the ends of the levers (shown in the diagram), and there is no friction, what is the acceleration of the sphere when = 30°
