The University of Michigan Department of Mechanical Engineering ME 320, Section 1 Homework #1 - Due September 17, 2008 Problem 1: (a) Problem 1.56 of Munson, Young, Okiishi, 5th edition (hereafter referred to as the text). (b) A 10-kg block is released from rest at t = 0 down a 20 o inclined surface, as shown in the Figure. Assuming that (i) the block slides on a 0.1mm ±lm of SAE 30 oil at 20 o C, (ii) the velocity distribution in the oil layer is linear, and (iii) the area of the block in contact with the oil is 0.2m 2 , derive an expression for the speed of the block as a function of time and plot

Unformatted text preview: your result. What is the initial acceleration of the block? What is its terminal velocity? Problem 2: Problems 1.63 and 1.65 of the text. In each case, if the external torque is suddenly removed, how long does it take for the conical body or the circular plate to come to a complete rest? Problem 3: Problems 1.68 , 1.69 and 1.70 of the text. Problem 4: Problems 1.83 and 1.84 of the text. Problem 5: Problems 1.86 and 1.94 of the text....
