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.
Homework Answers
Mechanical advantage is ratio of load which is pulled and force that is applied
If mechanical advantage = 3
Applied force = 15 N
Load lifted = 15 x 3 = 45 N
Mass lifted = 45/g = 4.59 kg
2)
Compound pulleys have greater mechanical advantage as compared to single pulley so greater load can be lifted by applying less force in compound pulley system
Please rate it up thanks :)

2. In many mechanical positioning systems there is flexibility between one part of the system and another. The figure below depicts such a situation, where a force u(t) is applied to the mass M, and another mass m is connected to it.

Problem 3 (70 pts): Consider the mechanical system in Figure , the so-called "cart pendulum" system. The cart has a moving mass M, and is connected to a linear motor via a flexible coupling with stiffness K and damping B. An inverted pendulum of length1, negligible inertia and mass m is attached to the cart via a rotary actuator. If the pendulum damping coefficient is b, the linear actuator force is F and the rotary actuator torque is t 1)...

Consider the electromechanical dynamic system shown in Figure 1(a). It consists of a cart of mass m moving without slipping on a linear ground track. The cart is equipped with an armature-controlled DC motor, which is coupled to a rack and pinion mechanism to convert the rotational motion to translation and to create the driving force for the system. Figure 1(b) shows the simplified equivalent electric circuit and the mechanical model...
