The pulley has no appreciable mass or friction. - Draw a free-body diagram for masses. What is the MAXImum weight w that n Can the ? ramp this crate stationary on Œ Crate 30.0⁰ 22.0 ramp W = ? be used to hold

A flatbed truck slowly tilts its bed upward to dispose of a 95.0@kg crate. For small angles of tilt the crate stays put, butwhen the tilt angle exceeds u = 23.3°, the crate begins to slide. What is the coefficient of static friction between thebed of the truck and the crate?

Find the smallest possible force that the woman should pull to cause the crate to slide. Coefficientof static friction is 0.20.

(a) Calculate the tension (in N) in a vertical strand of spiderweb if a spider of mass 8.00 x 10-5 kg hangs motionless on it. (Enter a number.) (b) Calculate the tension (in N) in a horizontal strand of spiderweb if the same spider sits motionless in the middle of it much like the tightrope walker in the figure. 5.0° 5.0° T. y4 T. Ta The strand sags at an angle of 12.0° below the horizontal. (Enter a number.) Compare this with the tension in the vertical strand (find their ratio). (Enter a number.)

A 20 kg box rests on a horizontal surface. What is the minimum horizontal force that is required to cause the box to begin to slide if the coefficient of static friction is 0.34? What is the acceleration of the system if a person pushes the box with a force of 90N if the coefficient of knietic friction is 0.21?

A block of weight w is suspended from a rope tied to two other ropes at point O. One rope ishorizontally attached to a wall and the other is fastened to the ceiling. The angle betweenceiling and the rope is 60°. What are the tensions in each of the ropes? Assume the weights ofthe ropes and the knots are negligible. If the weight of the block is 100 N, what is the tension inthe ceiling rope?

A worker drags a crate across a factory floor by pulling on a rope tied to the crate. The worker exerts a force of 450.0 N on the rope which is inclined at 38.0° to the horizontal, and the floor exerts a horizontal force of 124.0 N that opposes the motion. Calculate the acceleration of the crate if its mass is 400.0 kg. Assume positive is to the right and up. What would its acceleration be if its weight were 400.0 N?

A person pushes on a stationary 125 N box with a force of 93N at 30 degrees below the horizontal. The coefficient of static friction between the box and the horizontal floor is 0.76.  what is the normal force on the box?  what is the friction force on the box? what is the largest the friction force could be? the person now replaces his push with a 93N pull at 30degrees above the horizontal. Find the normal force on the box in this case.
