A light string can support a stationary hanging load of 23.4 kg before breaking. An object of mass m = 2.77 kg attached to the string rotates on a frictionless, horizontal table in a circle of radius r = 0.817 m, and the other end of the string is held fixed as in the figure below. What range of speeds can the object have before the string breaks? 0≤V≤ m/s m
The Atwood machine consists of two masses hanging from the ends of a rope that passes over a pulley. The pulley can be approximated by a uniform disk with mass m, = 6.13 kg and 17.9 kg radius r, = 0.150 m. The hanging masses are m and mg = 12.9 kg. Calculate the magnitude of the masses' acceleration a and the tension in the left and right ends of the rope, Ti and TR, respectively. m/s? a = N Ti = m. MR TR
Two masses are connected by an ideal rope over a pulley. The rope has no mass or stretch. The pulley is frictionless but has mass Mp and radius R. M, is on an approximately frictionless slope with angle 0 =19°. %3D The masses are all equal, M1 = M2 Mp. %3D The pulley can be approximated by a hoop with I = Mp R2 %3D If the masses are released from rest (not moving), what is their speed after M2 has fallen a distance h = 2.4 m?
