The third and fourth stages of a rocket are coasting in space with a velocity of 16 000 km/h when a small explosive charge between the stages separates them. Immediately after separation the fourth stage has increased its velocity to va - 16039 km/h. What is the corresponding velocity v3 of the third stage? At separation the third and fourth stages have masses of 210 and 105 kg, respectively. 4th stage 3rd stage

Solve the problem. A 11-in. connecting rod in an engine connects the wrist pin of a piston at point A to the end of a second rod at point on the crankshaft. As the piston moves forward and back, the crankshaft is turned counterclockwise around point C. The stroke length of the engine is the distance that the piston travels (one way) with its cylinder. If the stroke length is 4 in., and the engine turns at 600 rpm, write a model representing the distance d (in inches) from A to the center of the crankshaft Cas a function of time t (in minutes). Assume that at t = 0, the piston is at its farthest point from the crankshaft. B B C C B A A stroke length

Q2. Figure Q2 shows a simple gear train. At the instant shown, a force F = 1100 N is applied at one end of a 0.175 m long lever, perpendicular to the length of the lever. The other end of the lever is attached to shaft 1, and so the lever turns shaft 1. Gear A is attached to shaft 1 and has 48 teeth, Gear A is meshed with gear B, which has 16 teeth. a) What is the gear ratio from gear A to gear B? The efficiency of power transmission between the two gears is 70%. The moment of inertia of shaft 1, including the lever and gear A is 1.05 kgm² and the moment of inertia of gear B is 0.15 kgm². The frictional torque on shaft 1 is 0.2 Nm and the frictional torque on gear B is 0.7 Nm. If, at the instant show, the lever is moving downwards with a velocity of 1.4 m/s and an acceleration of 0.15 m/s², determine: b) the torque transmitted to gear A. c) the torque transmitted to gear B. d) the power transmitted to gear B. 1100 N 1.4 m/s 0.15 m/s² ME22002 Lever 0.175 m Gear A Gear B Figure Q2 END OF…
