Learning Goal: To draw the free-body diagram of a point particle, use the equations of equilibrium to find unknown forces, and understand how frictionless pulleys affect the transfer of force in a cable. As shown, a mass is suspended from a cable that wraps around a frictionless and massless pulley. The cable connects to a linear elastic spring. For this problem, treat the pulley as a point particle at B.

The spring has a spring constant of k = 15.5 kN/m. The pulley is attached to the ceiling by rod BD that forms an angle = 62.5° with the ceiling.Draw the free-body diagram of the pulley. Recall that the pulley is massless. Start all forces at point B in the center of the pulley. Draw all forces as tensile forces, or pulling forces.

'A model for the elbow joint models the bicep muscle connecting to the horizontal forearm by a vertical tendon 4cm from the elbow joint. A mass m is held in the hand 30cm from the elbow joint. If the maximum tension that can be exerted by the tendon before injury occurs is 2250N, find the maximum mass that can be held in this way.' Im stuck on this question

Consider a person who momentarily puts all of their body weight on one leg when walking or running. The forces acting on the leg and the corresponding biomechanical model of the system are shown in Fig.- Prob. 10(a) and (b). Point O corresponds to the center of rotation of the hip joint. A is the connection point of the hip abductor muscle with the femur; point B is the center of gravity of the leg; and C is the point of application of the ground reactive force. The distances between point A and points O, B, and C are: a = 8.6 cm, b = 34.3 cm, and c = 89.4 cm. The angles formed by the femoral neck and the longitudinal axis of the femur with respect to the horizontal are alpha = 43° and beta = 79°, respectively. Furthermore, for this position of the person standing on one leg, it has been estimated that the magnitude of the force exerted by the hip abductor muscle is FM = 2062.6 N and its line of action forms an angle of theta = 69° with respect to the horizontal. If the magnitude of…
A block A of 10 kg attached to a spring with K=200 N/m is moving downward along the slope. At this position, the spring is un-stretched, and the downward velocsity is 5m/sec. The slope is at an angle of 30 degrees, and force, F is 100 N applied. Find the distance when block A stops.
An inextensible massless string goes over a frictionless pulley. Two weights of 100 N and 200 N are attached to the two ends of the string. The weights are released from rest, and start moving due to gravity. What is the tension in the string?
Hang a mass from a spring. We are interested in the moment where you pull the mass down (before you release it) to the highest point that the mass moves to. We also care about when the mass is moving its fastest. In this case, the best place to put the zero reference is where the mass is hanging before you pull on it. 1)Draw an LOL Diagram 2)What is the energy model equation? 3)Will energy be conserved? (i.e., does ΔEsys =0?)
An unknown mass m is attached to two identical springs. Each spring has a stiffness k = 10 N/m and an unstretched length of 3 m. The unknown mass is released from rest when the springs are horizontal and unstretched. The mass reaches its maximum velocity after falling 4 m. Use work-energy to find the maximum velocity.
5.31a shows a student pulling horizontally with a 100 N force on a rope that is attached to a wall. In 5.31b, two students in a tug-of-war pull on opposite ends of a rope with 100 N each. Is the tension in the second rope larger than, smaller than, or the same as that in the first?
PROBLEMS IN EQUILIBRIUM OF PARALLEL:
You have been contracted by a company to design a system for them. The system requires that you use a very elastic material but the materials available to you are Material A which has a Young’s Modulus of 210,000 N/mm2 and Material B which has a Young’s modulus of 12,500 N/mm2 Using the deflection and stiffness equation, which material will best suit the job?
Learning Goal: To be able to use the conservation of energy on a moving body to determine key characteristics of the mechanics of the system. A package of mass m = 0.50 kg is pushed across the surface by a jet of compressed air during an assembly-line process. The package is moved through a distance of s = 50.0 cm. The package and the surface are known to have a coefficient of kinetic friction of μk = 0.15. The package is initially at rest for this process. PART A: If the package must be moving at a speed of v = 20.0 cm/s when it has reached the distance of 50.0 cm, determine the average force that the jet of compressed air must supply to the package PART B: If it is now desired that the package is at rest when it has reached the distance of 50.0 cm, determine the average force that the jet of compressed air must supply to the package if the package is initially traveling in the s direction at a velocity of v = 16.5 cm/s. PART C: If the plant has changed the mass of the package…
