QUESTION 2 Two ropes, with tensions T1- 5 N and T2 - 2.5 N, pull on...
Two tensions are applied from opposite sides of a pulley as T1 = 20 N and T2=35 N. Pulley is a solid disc of radius 0.5 m and with mass m=4kg. Calculate moment of inertia of the pulley. Calculate its angular acceleration.
2. A uniform, solid cylinder with mass M and radius 2R is on an incline plane with angle of inclination of 6. A string is attached by a yoke to a frictionless axle through the center of the cylinder so that the cylinder can rotate about the axle. The string runs over a disk-shaped pulley with mass M and radius R that is mounted on a frictionless axle through its center. A block of mass M is suspended from the...
A uniform, solid cylinder with mass 5 and radius 2*1.8 rests on a horizontal table. A string is attached by a yoke to a frictionless axle through the center of the cylinder such that the cylinder can rotate about the axle at the center. The string runs over a disk-shaped pulley with mass 5 and radius 1.8 that is mounted on a frictionless axle through its center. A block of mass 5 is suspended from the free end of the...
a cylinder of m=0.53 kg and radiuS 0.32 m can rotate around an axis through its center. the cylinder moment of inertial is given by MR^2 /2. the cylinder is initially at rest. A force of 0.70 N is then applied tangentially at the edge of the cylinder. how many radians will the cylinder rotate through during the first 2.5 seconds that the force is applied
Question 2 (8 marks) Applied force A vertical pulley, of radius 0.4 meter, can rotate about a horizontal axle (axle has friction) that goes through its center. The rotational inertia of the pulley about this axle is 16 x 10 kg.m. The torque due to friction in the axle is constant, with magnitude 0.8 Nm. A vertical force, of constant magnitude 11.0 N, is continuously applied tangentially to the rim of the pulley as shown above. The pulley is initially...
A uniform plank of mass 30kg and length 20m is supported by two ropes T1 and T2 attached as shown on the diagram. Two masses 20kg and 25kg are suspended are shown to keep the plank in equilibrium. Find the tension T1 and T2 due to the two ropes. I'm having trouble with this question. Would love to see the actual work, so I can understand the concept. 4. A uniform plank of mass 30 kg and length 20 m,...
5. Consider the system illustrated in the figure. The pulley with radius R and moment of inertia I around its fixed axis is mounted on a frictionless axle which is fixed to the table. Th has one end fixed to the table, and the other end is attached to a massless inextensible rope. Th and a mass m hangs at its other end. Initially, the system is at rest e spring with stiffness constant k e rope passes over the...
cylinder of m= 0.53 kg and a radius 0.32 m is rotating around an axis through its center. the cylinder’s moment of inertial is given by MR^2/2. The cylinder initially at rest. A force of 0.70n is then applied tangentially at the edge of the cylinder. How many radians will the cylinder rotate through in the first 2.5 seconds that the force is applied?
Need a solution A woman whose mass is 70 kg stands at the rim of a horizontal turntable that has a moment of inertia 300 kg m^2 and radius of 2 m. the system is initially at rest and is free to rotate about frictionless vertical axle through the center of the turntable. The woman begins to walk clockwise around the rim at a speed 1.5 m/s relative to the earth. In what direction and with what angular speed does...
The ropes in (Figure 1) are each wrapped around a cylinder, and the two cylinders are fastened together. The smaller cylinder has a diameter of 10 cm and a mass of 2.0 kg ; the larger cylinder has a diameter of 20 cm and a mass of 12 kg . What is the angular acceleration of the cylinders? Assume that the cylinders turn on a frictionless axle. 2 x P The BBS SUL PH Be Me 3b 65 C An...
