Shown below is a leg in a cast and supported by two cables. The combined weight of the leg and cast is 150N acting at the center of mass as shown. The angle of the ankle cable is 60 degrees from the horizontal and the angle of the knee cable is 45 degrees from the horizontal, as shown. Find the cable tensions Tk and TA.

A truck bed cargo shell has a rectangular glass window that is held up by two strut pistons. Assume the glass window is 0.483 m long and has a mass of 11.3 kg. Each piston is connected to the window 0.153 m from the glass' pivot point and makes an angle of 0, 22.5° with the glass. A mass-free rope is attached at the end of the glass making an angle of 62 = 43.5°. A box with mass, m, hangs from the end of the rope. Each of the pistons can exert a force of 228 N when fully extended. a) Find the maximum mass the box can be before the glass window begins to close. b) Find the tension in the rope. pivot point glass 02 camper rope shell 01 pistons (2)
The lumbar portion of the human spine supports the entire weight of the upper torso and the force load imposed on it. We consider here the disk (shaded red) between the lowest vertebra of the lumbar region (L5) and the uppermost vertebra of the sacrum re- gion. (a) For the case L = 0, determine the com- pressive force C and the shear force S supported by this disk in terms of the body weight W. The weight W. of the upper torso (above the disk in question) is 68% of the total body weight W and acts at Gj. The vertical force F which the rectus muscles of the back 25 mm L3 L4 L5 G2 4r exert on the upper torso acts as shown in the figure. (b) Repeat for the case when the person holds a weight of magnitude L assumptions. W/3 as shown. State any Sacrum %3D 300 mm 50 mm 3王

Consider why a wheelbarrow is helpful to move heavy stuff. Below is an example wheelbarrow loaded with 15 kg of stuff. 9. 1.25 m Center of mass € 0.45 m of body and handle Fx Fy 1.20 m 0.55 m 0.30 m The wheelbarrow has a single wheel of mass 2.5 kg, radius of 0.30 m. The body of the wheelbarrow and the stuff has a combine mass of 17.5 kg acting at the center of mass shown. The horizontal and vertical components of the force that we push with is named F and Fy, respectively. a. Draw separate free body diagrams for the wheel and for the wheelbarrow body. b. What force F and F, do you have to apply to the wheelbarrow to accelerate the wheelbarrow at 1.0 m/s2 to the right? (Hint: The body of the wheelbarrow does not rotate.)

A uniform aluminum beam 9.00 m long, weighing 300 N,rests symmetrically on two supports 5.00 m apart (Fig. ). A boyweighing 600 N starts at point A and walks toward the right. (a) In thesame diagram construct two graphs showing the upward forces FA andFB exerted on the beam at points A and B, as functions of the coordinatex of the boy. Let 1 cm = 100 N vertically and 1 cm = 1.00 m horizontally.(b) From your diagram, how far beyond point B can the boy walkbefore the beam tips? (c) How far from the right end of the beam shouldsupport B be placed so that the boy can walk just to the end of the beamwithout causing it to tip?

A uniform ladder stands on a rough floor and rests against a frictionless wall as shown in the figure. N2 mg Since the floor is rough, it exerts both a normal force N, and a frictional force f, on the ladder. However, since the wall is frictionless, it exerts only a normal force N, on the ladder. The ladder has a length of L = 4.7 m, a weight of W, = 57.5 N, and rests against the wall a distanced = 3.75 m above the floor. If a person with a mass of m = 90 kg is standing on the ladder, determine the following. (a) the forces exerted on the ladder when the person is halfway up the ladder (Enter the magnitude only.) N = N2 N N (b) the forces exerted on the ladder when the person is three-fourths of the way up the ladder (Enter the magnitude only.) N, = N2 N %3D N
