Question 2) The figure shows a mechanical model of the Russel fracture traction device and the leg. The leg is held in balance in the position indicated by the two weights attached to the two cables. The combined weight of the leg and the cast is W=210 N. The horizontal distance between points A and B where the cables are attached to the leg is L=100 cm and the vertical distance is d=6 cm. Point C is the center of gravity of the cast and leg at three quarters of the L measured from point A (3L/4= 75 cm). The angle that cable 2 makes with the horizontal is measured as β=33°. Accordingly, in order for the leg to remain in balance in the shown position; a) Find the tensile force T1 in cable 1. (Write your result in N) b) Find the tensile force T2 in cable 2. (Write your result in N) c) Find the angle α of cable 1 with the horizontal. Response
One end of a uniform 2.60m rod with a mass of 38.0kg is supported by a cable connecting one end to the wall so that the cable makes an angle of 42.0° with respect to the rod. The other end rests against the vertical wall, where it is held in place by friction so that the rod is perfectly horizontal. A sign with an unknown mass is hung from the rod 1.90m from the wall so that wall exerts a normal force of 1790N on the rod in the positive x-direction. What is the mass of the sign in kilograms?

A beam resting on two pivots has a length of L = 6.00 m and mass M = 94.0 kg. The pivot under the left end exerts a normal force n1 on the beam, and the second pivot placed a distance ℓ = 4.00 m from the left end exerts a normal force n2. A woman of mass m = 51.5 kg steps onto the left end of the beam and begins walking to the right as in the figure below. The goal is to find the woman's position when the beam begins to tip. (a) Sketch a free-body diagram, labeling the gravitational and normal forces acting on the beam and placing the woman x meters to the right of the first pivot, which is the origin. (b) Where is the woman when the normal force n1 is the greatest? x = _____m(c) What is n1 when the beam is about to tip?____N(d) Use the force equation of equilibrium to find the value of n2 when the beam is about to tip.____N(e) Using the result of part (c) and the torque equilibrium equation, with torques computed around the second pivot point, find the woman's position when the beam…

I need your help expert. The system shown below is in equilibrium. Spring 3 is known to have a change in length of 10 cm. The magnitude of the compressive force in Spring 2 is 15% more than the magnitude of force P, while the magnitude of the compressive force in Bar 1 is 100 N less than that in Spring 2. If the spring constants of Springs 2 and 3 are 625 and 1200 N/m, respectively, determine the following: a. magnitude of forces P (in N) and F (in N) b. tension (in N) in cable ABC c. mass (in kg) of Block A d. compressive force in Bar 1 e. change in length (in cm) of Spring 2 Draw the complete FBD’s of Block A, Hook C and Pulley E.
