In about 1915, Henry Sincosky of Philadelphia suspended himself from a rafter by gripping the rafter with the thumb of each hand on one side and the fingers on the other side (see the figure). Sincosky's mass was 81.0 kg. If the coefficient of static friction between hand and rafter was 0.730, what was the least magnitude of the normal force on the rafter from each thumb or opposite fingers? (After suspending himself, Sincosky chinned himself on the rafter and then moved hand-over-hand along the rafter. If you do not think Sincosky's grip was remarkable, try to repeat his stunt.)

Let's say you have two boxes made of the same material. Into one box you put a lot of weight and into the other you put a small amount of weight. You then put both boxes onto the same board and raise one end to make an incline. Should there be a difference in the measured coefficients of static friction for the two boxes? Why or why not?
A box of bananas weighing 40.0 N rests on a horizontal surface.The coefficient of static friction between the box and the surfaceis 0.40, and the coefficient of kinetic friction is 0.20. If no horizontal force is applied to the box and the box is at rest, how large is the friction force exerted on it?

A man standing on the ground exerts a horizontal force of 439 N when pushing on his friend standing on the skateboard.If the friend’s mass is 70 kg, the skateboard’s mass is 2 kg, and the coefficient of static friction between the friend’sfeet and the skateboard is 0.8, calculate the magnitude of the force of static friction between the skateboard and thefriend’s feet. You can assume that the wheels on the skateboard are good enough so that you can neglect frictionbetween the wheels and the ground.
