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 ten 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 pain

explanation: in any substance/object, the particles inside it (atoms/molecules) constantly move in random directions and with random speeds (this motion is called brownian motion). as a result, the particles have some kinetic energy (which is proportional to the temperature of the substance).

explanation:

have a great day!

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever

i think it would be 5

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
