Block A lies on the top of block C and is connected with block B by a massless unstretchable string passing over a massless and frictionless pulley. Block B is also in contact with the block C (see picture). Masses of blocks A and B are the same MĄ =mg =m and the coefficient of friction between each of them and block C is µ. (a) What should be a constant acceleration a in horizontal direction from the left to the right of the whole system in order that blocks A and B do not move with respect to the block C? (b) What will be an acceleration of the blocks A and B if the whole system initially is at rest and then blocks A and B are released and start moving? (Hint: in both cases start with free body diagrams for blocks A and B)

2: The lecturer Aous used to drive his car early inorder to arrive and teach his students some engineering subjects in Tikrit University because he lives in Baghdad. The distance between the above two cities (Tikrit and Baghdad) is 160 km, and he always drive in average velocity which is about 75 mile per hour. Determine the time that he should start driving from Baghdad if you know that the first lecture begins at 8:30 a.m Hint: one mile is almost equal to 1.6 km
The center of mass of an object: Must be located on the object. Generally coincides with the center of gravity for objects considered in engineering analysis if the gravitational field fo all parts of the object is uniform and parallel. Depends upon the variation of the value and direction of the force of gravity for each part of the object. Is always at the same point as the center of gravity.

1. Define a force of 1 newton and 1 pound with the help of a figure.
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-
