The slender-bar assembly B (Figure 4) has a mass per unit length of 5 kg/m and is mounted on the shaft A. The shaft is subjected to a torque of M = 0.5/t N•m (where t is in seconds). Calculate the angular velocity of the assembly B when t=3 s, starting from rest. Neglect the mass of shaft A. 500 mm |A M 100 mm 100 mm

The two 1-kg gears A and B are attached to the ends of al 3-kg slender bar. The gears roll within the fixed ring gear C, which lies in the horizontal plane. (Figure 1) Figure 150 mm 400 mm- 150 mm Part A If a 10-N m torque is applied to the center of the bar as shown, determine the number of revolutions the bar must rotate starting from rest in order for it to have an angular velocity of WAB = 22 rad/s. For the calculation, assume the gears can be approximated by thin disks. Express your answer using three significant figures. ►View Available Hint(s) the number of revolutions = Submit Provide Feedback VAE vec ? Next >

Can anyone help me with this question

Please answer this NEATLY, COMPLETELY, and CORRECTLY for an UPVOTE. The mass of gear A is 20 kg and its centroidal radius of gyration is 150 mm. The mass of gear B is 10 kg and its centroidal radius of gyration is 100 mm. Calculate the angular acceleration of gear B when a torque of 57 N-m is applied to the shaft of gear A. Neglect friction.

A relatively thin disc with uniformly distributed mass is mounted on a shaft which rotates at 1000 RPM. To conduct a test, two extra masses are added to the disc at the positions shown in Figure Q10. Masses A and B introduce known unbalances of 2 kgmm and 4 kgmm, respectively. Determine the angular location of the correction mass measured from y-axis in the clockwise direction and the centrifugal force that it needs to produce in order to balance the system.

The 16-kg wheel is rolling under the constant moment of M = 60 N-m. The wheel has radius r= 0.50 m, has mass center at point G, and the radius of gyration is kg = 0.23 m. The coefficients of friction between the wheel and the ground is ls = 0.28 and Uk = 0.14. If the wheel rolls without slipping, determine the angular acceleration of the wheel (in rad/s?). Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point. Take g = 9.81 m/s?. M

The wheel has a mass of 100 kg and a radius of gyration of ko = 0.2 m. A motor supplies a torque M = (400 +900) N - m where is in radians, about the drive shaft at O. Initially the car is at rest when s = 0 and 0 = 0°. Neglect the mass of the attached cable and the mass of the car's wheels. (Figure 1) Figure 94°F Sunny M KI 0.3 m 1 of 1 Pro
