What is the mechanical advantage of the pulley system shown below? Explain.
A pulley system has a mechanical advantage of 18. If one is trying to raise a piano with a mass of 380 kg at a constant velocity a distance of 2.8 meters, how many meters of the rope must be pulled?
1. Consider a pulley system with a mechanical advantage of 3 connected to a mass moving with a constant velocity. Calculate the mass of the object if the applied force is 15 N. Show your work. 2. Compare the efficiencies of single pulley systems and compound pulley systems. Which type of system is more efficient on average and why? I NEED TYPED ,WELL EXPLAINED SOLUTION FOR THESE BOTH QUESTIONS.
help anyone? 8. Determine the mechanical advantage for each of the pulley systems below
3) A piano of 600kg, is being lifted by a pulley with a mechanical advantage of 10. a) How much force would it require for the pulley to lift the piano? b) How much of the rope is pulled if the piano is being lifted at a constant velocity to a height of 8.4m?
10. A pulley and mass system is setup as shown below. The pulley is not massless, but you may assume there is no slipping of the string along the pulley and that the string is massless. The system starts from rest and the hanging mass is seen to move upwards. There is a tension T1 in the left portion of the string, and a tension T2 in the right portion of the string. Is the magnitude of T larger or...

A pulley system is attached to a massless board as shown below. The board pivots only at the pivot point. A 10 kg mass M sits exactly in the middle of the board. If the angle is 30°, what is the force necessary to lift the 10 kg mass? 46. A pulley system is attached to a massless board as shown below. The board pivots only at the pivot point. A 10 kg mass M sits exactly in the middle...
Find the transfer function (X/F) for the mechanical system shown below
As shown, a frictionless pulley hangs from a system of springs and a cable. The pulley is equidistant between the two supports attaching the springs to the ceiling. The distance between the supports is d=1.50 m . The cable cannot stretch and its length between the two springs is 1.8 m. (figure 1) (FIgure 2) A)As shown, a mass is hung from the pulley. This mass causes a tensile force of 17.0 N in the cable and the pulley to...
