In a home laundry dryer, a cylindrical tub containing wet clothes is rotated steadily about a horizontal axis, as shown in the figure below. So that the clothes will dry uniformly, they are made to tumble. The rate of rotation of the smooth-walled tub is chosen so that a small piece of cloth will lose contact with the tub when the cloth is at an angle of θ = 74.5° above the horizontal. If the radius of the tub is r = 0.455 m, what rate of revolution is needed in revolutions per second?**Figure Description:**The figure is a side view of a cylindrical tub, showing clothes tumbling inside it. The tub is rotating in the clockwise direction. An angle θ = 74.5° is marked above the horizontal line passing through the center of the tub. The radius of the tub, r, is given as 0.455 meters.

A 0.50-kg ball that is tied to the end of a 1.4-m light cord is revolved in a horizontal plane, with the cord making a θ = 30° angle with the vertical. An illustration shows a ball suspended from a string. The string forms an angle θ with the vertical as its top end is held stationary in space while the ball moves along a horizontal circular path below. The center of the circular path is shown to be directly below the top end of the string. (c) If the cord can withstand a maximum tension of 8.9 N, what is the highest speed at which the ball can move?
You have a bucket, which you fill with some water (the amount does not change the answer). You whirl the bucket in a circle of radius 0.72 m. Calculate the minimum tangential speed the water must have at its highest point, in m/s, so that it doesn't fall out of the bucket. (Please answer to the fourth decimal place - i.e 14.3225)
Water parks often include a log rolling area, in which participants try to stay upright while balancing on top of floating logs that are free to rotate in the water. If you’ve tried this, you know that the larger the diameter of the log, the easier it is to balance on top. Explain why this is so.
You have a summer internship at NASA and are working on plans for a new space station to be launched into orbit around the Earth. The design of the space station is shown. It is to be constructed in the shape of a hollow ring of mass 51,500 kg. The structures other than the ring shown in the figure have negligible mass compared to the ring. Members of the crew will walk on a deck formed by the inner surface of the outer cylindrical wall of the ring, with radius r = 120 m. The thickness of the ring is very small compared to the radius, so we can model the ring as a hoop. At rest when constructed, the ring is to be set rotating about its axis so that the people standing inside on this deck experience an effective free-fall acceleration equal to g. The rotation is achieved by firing two small rockets attached tangentially to opposite points on the rim of the ring. Your supervisor asks you to determine the following: (a) the time interval during which the rockets must be fired if each…
a bucket of water with a mass of 25 kilograms is lifted from a well by a rope which is wound around a cylinder with a radius of 0.10 meters. A 0.50 meter crank is attached to the cylinder so that it wraps the rope around the cylinder. what is the minimum force that must be applied to the crank to lift the water bucket ?
Jackson finds an old well with a rope, bucket, a shaft that spools the rope, and a large crank wheel that turns the shaft to bring up the bucket of water. The bucket and the water have a total mass of 10.33kg, the shaft has a diameter of 15cm, and the crank wheel has a radius of 0.625m. Ignoring the mass of the rope, use torque to find the tangential force on the crank wheel required to lift the bucket and the water at a constanst speed.

An air puck of mass m1 = 0.27 kg is tied to a string and allowed to revolve in a circle of radius R = 1.1 m on a frictionless horizontal table. The other end of the string passes through a hole in the center of the table, and a mass of m2 = 0.8 kg is tied to it (see the figure below). The suspended mass remains in equilibrium while the puck on the tabletop revolves. An overhead view of a table is shown. A string is used to whirl a puck of mass m1counterclockwise with velocity vector v on a horizontal circular path of radius R on the surface of the table. The string passes through a hole at the center of the circular path, and then extends down under the table where an object of mass m2 is attached. (a) What is the tension in the string (in N)? N (b) What is the horizontal force acting on the puck (in N)? N (c) What is the speed of the puck (in m/s)? m/s
