The cart on the table has a mass of 0.40 kg and is attached by a string and a pulley, to a weight that has a mass of 0.20 kg. Calculate the a) acceleration if there is a frictional force of 0.10 N acting on the cart and the b) magnitude of the tension in the string.

The rigid beam is supported by the three suspender bars. bars ab and ef are made of aluminum and bar cd is made of steel. if each bar has a cross-sectional area of 450 mm2, determine the maximum value of p if the allowable stress is (σallow)st = 200 mpa for the steel and ( σallow)al = 150 mpa for the aluminum. est = 200 gpa and eal = 70 gpa.
