A force of magnitude F N is applied to a block of mass M kg which is initially at rest on a horizontal plane. The block starts to move F N with acceleration 3 m s². Modelling the block as a particle, (i) if the plane is smooth, find an expression for F in terms of M. If the plane is rough, and the coefficient of friction between the block and the plane is µ, (ii) express F in terms of M, µ and g. (iii) Calculate the value of µ if F = Mg.

State one word problem and solve it wherein the ideal mechanical advantage of a wedge is being solved. Use the formula, IMA = (Length of the Widge) divided by (Width of the Wedge). note: please do not forget to include your solution in solving the problem.
Fluid Force. A swimming pool is filled with fresh water to a depth of 7 feet measured at the deep end. There is not enough water in the pool to reach the shallow end. Assume that the pool is constucted using right angles, except where the bottom of the pool meets the end walls. Use Ah for the height of a typical strip across the face of the wall. 6. The weight density of water is 62.4 lb/ Your anwers should have units: pounds. 4 ft 18 ft 24 ft Declare your variable(s) here. Show your reasoning below: a) find the force on the typical horizontal strip (red) ? b) write an integral for the total force on the (left) wall of the pool
Paula has worked for Brindle Corporation for 3 years. During this time, she has worked as a machine operator/cell leader in various work cells. Recently, the plant went to mandatory 12-hour shifts and plans to remain on this schedule for several months. Paula’s present work cell is manufacturing 3-inch diameter exhaust tubes that are made from stainless steel. These tubes get a hole punched in them, a flange welded on, and burrs ground off. The pipe then gets placed into a gage to check that it was made correctly. (The tubes weigh about six pounds.) Paula has been performing the welding operation. She leans into the machine and loads the part into a fixture then positions the flange. Both pieces are clamped (using hand clamps) into position and the machine is cycled by depressing two palm buttons. The gaging operation requires placing the finished part into the gage and clamping it (using hand clamps) into place. A pin is depressed to verify the position of the hole and a…
