Two masses hang on opposite ends of a rope suspended over a pulley. The pulley is restrained from rotating and the two forces: - (the force of tension exerted by the rope on mass A) and TB (the force of tension exerted by the rope on mass B) are found to be equal in magnitude. If the pulley becomes free to rotate and the system begins moving, the relationship between those forces becomes |Fra| > |F| b. Fal < |F| d. a. Fral = |F| e. TB ТА TB TA TB C.

- A 29 kg mass is connected to a nail on a frictionless table by a massless string 1.5 m long. There is no appreciable friction between the nail and the string. If the tension in the string is 57 N while the mass moves in a uniform circle on the table, how long does it take for the mass to make one complete revolution? (Give answer to the nearest 0.1 s) Please explain how to get the answer, thank you :)An astronaut hangs on to a handrail on the rim of a disk-shaped space station that has a radius of 16 m and rotates once in 30 s. (a) What force must the rail exert on the astronaut? (Express this force as a fraction of the astronaut’s normal weight on the earth’s surface.) The rail must exert a force which is % of the astronaut’s normal weight. (b) What is the net force on the astronaut (expressed in the same way)? The net force on the astronaut is the (Click to select)( inward handrail force or outward handrail force) .3. The member OA rotates in vertical plane about a horizontal axis through O with a constant counter clockwise velocity w=3 rad/s. As it passes the position 0=0, a small mass m is placed upon it at a radial distance r=0.5 m. If the mass is observed to slip at 0=37°, find the coefficient of friction between the mass and the member. Answer: uk = 0.1875 Solution Ө

What is the tension acting on the rope at the end (i.e value of F3)?One end of a string is wrapped several times around a pulley of mass 0.92 kgkg that is oriented vertically. The other end of the string is connected to a block of mass 0.35 kg, which is then slowly lowered until the string becomes taut.
