Two blocks A and B, each having a mass of 5.5 kg , are connected by pins using the linkages shown. A В 0, 02 The coefficient of static friction between Block A and the floor is u A= 0.21. The coefficient of static friction between Block B and the floor is µB= 0.44. The angles given are 01 = 45 degrees 02 = 28 degrees Neglect the weight of the links. i. Draw the Free Body Diagrams for pin C, Block A, and Block B. ii. Applied force P on pin C is gradually raised. Which block starts slipping first and what is the value of P when slippage starts occurring? Hint: It helps to establish two cases, one in which block A slips and one in which block B slips, and then calculate what occurs in each case in order to determine what happens. Part A - Part A Draw the Free Body Diagram for link C. Note that for this problem we are looking at the starting location of the vectors. Draw the vectors starting at the gold dot at point C. The location of the starting point as well as the orientation of your…

A hole is to be drilled as shown by the circle. Using the part geometry shown below, indicate on the part sketch where locator(s) should be positioned according to the 3-2-1 principle. Use dashed lines to indicate locators on hidden surfaces. Also indicate where clamping force(s) should be applied using arrows. Use the minimum number of clamping forces.
Draw front and right-side views of the following object with a completed dimensions. Draw in scale 1:1 on A4 sheet. (Problem is taken from "Graphics for Engineers' by Earle) 78 What can we learm from the drawlng ? 1. The dimension note M10x1.5 means that the hole is a threaded hole. R16 O 16, 2 Holes The letter 'M' means that the threads are made by following a metric thread system. The number "10" Is the major dlameter of the hole and the number 1.5 is the pitch of a thread. However, for coarse threads, it is a common practice to omit specifying the pitches. For example, a note M10 means the pitches of the thread is 1.5 mm. In this book, the pitch is specified in order to facilitate drafting. 2.
