A 6-m long x 50-mm-diameter rod of aluminum alloy [E = 70 GPa, v = 0.346, and a = 22.5 x 10-6/°C] is attached at the ends to supports that yield to permit a change in length of 1.00 mm in the rod when stressed. When the temperature is 35°C, there is no stress in the rod. After the temperature of the rod drops to -20°C, determine a. The normal stress in the rod. Ans. 74.96 MPa (T) b. The change in diameter of the rod. Ans. +0.0228 mm

Can someone please help me to solve only number 7 and number 8 of this question. Thank you!

Design a Geneva Mechanism for an eight station automated tables. The indexer diameter is set to 36 in and the station cycle time is 40s. Show both the design drawing and calculations

Learning Goal: To understand how to use the relative position and velocity equations to find the linear and angular velocity of members in an assembly. A piston is driven by a crankshaft as shown. The crank arm (member AB) has a length of r₁=0.55 in and the connecting rod (member BC) has a length of r2 = 4.25 in. The crankshaft rotates in the counterclockwise or positive direction. (Figure 1) Figure C 1₂ @₂ @1 0 B X 1 of 2 Part C - Velocity of C Find the magnitude of the velocity of C, vc, when the piston has moved to the new position = 33.0° and p = 6.23°. The crankshaft (member AB) is still rotating at 300 rpm Express your answer to three significant figures and include the appropriate units. ► View Available Hint(s) vc= 15.5 in S Submit Completed Part D - Rotational Speed of the Crankshaft W1 = Previous Answers The velocity of the piston is vc = 70.0 in/s j the instant when 0 = 33.0° and = 6.23°. Find the rotational speed of the crankshaft (member AB) at this instant. The crankshaft…
