Problem 1 The 75-pound escape hatch is held open by journal bearing A, thrust bearing B, and thin link CD. Determine the support reactions. The coordinates of each point are given below. All coordinates are in inches. A: (0, 0, 60) B: (0, 72, 60) C: (40, 50, 60) D: (50, 70,0) Center of Gravity: (30, 36, 60) Problem 1 The member shown is supported by a pin at A and cable BDC. Determine the support reactions. You may ignore the thickness of the object. Pulley D 75° 40 kip-ft 01 12 kip 15' 8'

A manager checked production records and found that a worker produced 186 units while working 60 hours. In the previous week, the same worker produced 130 units while working 50 hours. a. Compute Current period productivity and Previous period productivity. (Round your answers to 2 decimal places.) Current period productivity Previous period productivity Units/hour Units/hour b. Did the worker's productivity increase, decrease, or remain the same? (Round your intermediate calculations and final answer to 2 decimal places.) Worker's productivity by %

Please make the charts for the questions. Please refer to Successful Project Management (7th Edition). Attached is the example Thank you.

Please provide more details for question b and c.  thank you

71.7 is being marked wrong in McGraw Hill homework. I thought I had done it right with putting 86.03 but that is wrong also. I'm not trying to just find the answer, trying to find how to do this. Could there be a different number than 71.7? Where does the μk=0.20 come into the equation?

Please give a steps by steps explanation of each question answer please. Thanks you so much

A manufacturer claims that the average tensile strength of thread A exceeds the average tensile strength of thread B by at least 12 kilograms. To test this claim, 50 pieces of each type of thread were tested under similar conditions. Type A thread had an average tensile strength of 86.7 kilograms with a standard deviation of 6.28 kilograms, while type B thread had an average tensile strength of 77.8 kilograms with a standard deviation of 5.61 kilograms. Test the manufacturer’s claim using a 0.05 level of significance. 1. Determine the Z calculated in two decimal places. 2. Determine the Z table in two decimal places. 3. Is the manufacturing claim statistically valid? yes or no

Can someone help me to solve the following problem showing all work thank you!
