- Can anyone help me with this questionarrow_forwardThe system shown below consists of a uniform disk D that has a mass of mp = 3.0 kg and a radius of r = 0.5 meters. The disk is connected by a massless cable to a block. The system is released from rest and the disk starts rolling without sliding with the angular acceleration of a = 24 rad in the clockwise direction. Determine the tension developed in the cable (in Newtons) at this instant. Consider 0 = 30° and g 10 * mparrow_forwardThe 100 kg cylinder has an angular velocity of 30 rad/s If the coefficient of kinetic friction is 0.2.

- The system is made up of the 1-m, 6.5-kg uniform rod AB and the two uniform disks (each of 0.19 m radius and 1.5 kg mass). If the system is released from rest when = 80°, when rod AB has just become horizontal, determine the coefficient C in the expression Cw² which is the kinetic energy of rod AB at this instant. Assume the disks roll without slipping. Your answer must include 2 places after the decimal point. Please pay attention: the numbers may change since they are randomized. AB' Take g= 9.81 m/s². A-L B m Your Answer: Answerarrow_forwardThe 2.28-kg uniform slender bar rotates freely about a horizontal axis through O. The system is released from rest when it is in the horizontal position 0 = 0 where the spring is unstretched. If the bar is observed to momentarily stop in the position 0 = 66°, determine the spring constant k. For your computed value of k, what is magnitude of the angular velocity of the bar when 0 = 48°.

- The system shown below consists of a uniform disk D that has a mass of mp = 3.0 kg and a radius of r = 1.0 meters. The disk is connected by a massless cable to a block. The system is released from rest and the disk starts rolling without sliding with the angular acceleration of a = rad 30 s2 in the clockwise direction. Determine the magnitude of the friction force (in Newtons) developed between the disk and the inclined surface at this instant. Consider 0 = 40° and g = 10 m. mparrow_forwardThe 45-kg reel has a radius of gyration about its center O of ko = 220 mm. If it is released from rest, determine the total external work done to it when its center O has traveled 6.6 m down the smooth inclined plane (with angle = 35°). Please pay attention: the numbers may change since they are randomized. Your answer must include 1 place after the decimal point, and proper SI unit.
