Q1} The coefficient of friction, µ can be determined in an experiment by measuring the force F required to move a mass m. when F is measured and m is known, the coefficient of friction can be calculated by H = F/mg (g=9.81 m/s?) results from measuring F in six tests are given in the table below write Excel program to determine the coefficient of friction in each test, and the average for all tests

The pipe assembly of the figure is supported by a fixed support at point A. A couple-moment and a force are applied at points B and C, respectively. In Cartesian coordinates, the applied couple-moment is MB = -150 k N-m, and the applied force is Fc = + 200ĵ Newtons. You may neglect the weight of the pipe assembly. 1. Draw a FBD which is suitable for solution of this problem, when seeking the unknown force and moment reactions at the fixed support, Point A. You may use the existing drawing given below. Your FBD must clearly/correctly show the force and moment reaction vectors. Use double arrowheads to distinguish moment vectors from force vectors. 2. Calculate F°MA, which is the moment generated at A due to the force applied at Point C. 3. Write the equations of equilibrium and solve to find the reactions at Point A. Specifically, find the force-reaction vector, A and the moment-reaction vector, *MA-
