A block of mass 4.20 kg is pushed up against a wall by a force P that makes an angle of θ = 50.0°angle with the horizontal as shown below. The coefficient of static friction between the block and the wall is 0.270.
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 opposite side. Sincosky’s mass was 79 kg. If the coefficient of static friction between hand and rafter was 0.70, 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.)
If a box on a horizontal surface has an externally applied horizontal force that exceeds the value of the static frictional force, the box is defined to be.
