(a) What is the maximum frictional force in the knee joint of a person who supports 66.0 kg of her mass on that knee? (b) During strenuous exercise, it is possible to exert forces to the joints that are easily 10 times greater than the weight being supported. What is the maximum force of friction under such conditions? The frictional forces in joints are relatively small in all circumstances except when the joints deteriorate, such as from injury or arthritis. Increased frictional forces can cause further damage and pam.
We tie an 80 cm long rubber cord to the ceiling and attach a 50 g weight o its other end. The cord gets extended by 4.0 cm. We raise the weight to the ceiling and let it down. What is the force of the string, when the weight reaches its lowest point?

A push of magnitude P acts on a box of weight W as shown in the figure. The push is directed at an angle 0 below the horizontal, and the box remains a rest. The box rests on a horizontal surface that has some friction with the box. The normal force on the box due to the floor is equal to: O W + P cos 0. O W + P sin 0. OW-P sin 0. O W + P. O W. W 0 P
A 1.70 kg box rests on a plank that is inclined ut an angle of 63.0° above the horizontal. The upper end of the box isattached to a spring with a force constant of 16.0 N/m, as shown in the figure. If the coefficient of static friction betweenthe box and the plank is 0.26, what is the maximum amount the spring can be stretched and the box remain at rest?
