Determine the force P required to maintain the 200-kg engine in the position for which 0 = 30o. The %3D diameter of the pulley at B is negligible ( take g=10 m/s2)

3. The pneumatic jack is used in a service station as shown in the figure below. If the car and lift weigh 5000 lb, determine the force that must be developed by the air compressor at B to raise the lift at a constant velocity. Air is in the line from B to A. The air line at B has an inner diameter of 1 in., and the post at A has a diameter of 12 in. apapay A 12 in. 1 in. B

Balance three masses that lie in one plane as shown below, if it is known that m1 = 2 Kg ; R1 = 150 mm ; θ1 = 45°; m2 = 1 Kg ; R2 = 200 mm ; θ2 = 85⁰ and m3 = 3 Kg R3 = 50 mm θ3 = 160°. Find the balancing masses me and e if Re = 100 mm

The horizontal steel shaft has a mass of 360 kg and is suspended by a vertical cable from A and by a second cable BC which lies in a vertical transverse plane and loops underneath the shaft. Calculate the tensions T1 and T, in the cables. 1.0 m 1.0 m B. T2 Т T1 2.0 m -1.9 m 2.6 m 0.6 m Answers: N T1 = i N T2 = i
