The University of Michigan Department of Mechanical Engineering ME 320 - Sections 1 & 2 Homework #1 - Due September 21, 2011 Problem 1: Problems 1.11 , 1.12 and 1.13 of Munson, Young, Okiishi, Huebsch, 6th edition (hereafter referred to as the text) Problem 2: (a) Problems 1.60 and 1.62 of 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 film of SAE 30 oil at 60 o F, (ii) the velocity distribution in the oil layer is linear, and (iii) the area of the block in contact with

Unformatted text preview: the oil is 0.1m 2 , derive an expression for the speed of the block as a function of time and plot your result. What is the initial acceleration of the block? What is its terminal velocity? Problem 3: Problems 1.69 , 1.70 and 1.71 of the text. In each case, if the external torque is suddenly removed, how long does it take for the rotating body to come to a complete rest? Problem 4: Problems 1.77 , 1.79 and 1.80 of the text. Problem 5: Problems 1.97 , 1.99 and 1.103 of the text....
