A father lifts his child as shown in the figure below. How much torque does the child exert, taking the knee as the pivot? How much torque does the weight of the leg itself exert? What force () should the upper leg muscle exert to lift the child at a constant speed?
4) The figure below is a testing device used to measure the coefficient of friction between two materials (although it looks a bit like a record player). The disk is rotating at -20k rad/s and the length of the arm is 0.3m. At t = 0 the arm is put into motion with a rotational speed of 10k rad/s and the timer records how long it takes for the arm to reach a speed of rotation equal to that of the disk. Assume the elapsed time is 2.5 s. The normal force between the tip and the disk is 2N and lo = 0.015 kg-m2. a) Explicitly define the correct coordinates for the rotating system and write out the corresponding transformation array. b) Draw an FBD and IRD for the system. c) Calculate the coefficient of friction.

Two weights are hung over two frictionless pulleys that are connected by a wire rope to a 500 Ib horizontal block that are in between and below them. The wire rope attached to the upper left end of the block and to the left pulley is at 45 degrees with the horizontal and the wire rope that connects the upper right end of the block to the right pulley is at 30 degrees with the horizontal. If the weight on the left pulley is 50 lb, fs= 0.30 and fk = 0.20 on the surface of block what weight W on the right pulley will cause the 500 lb block to just start moving to the right? *
