hi. can you please help me solve this as for my understanding.. our topic is about Moment of Inertia and I can't understand how it is solve. pls provide a diagram with labels. Thank you 1. Three masses A= 3kg, B= 4kg, and C= 5kg are connected by rods of negligible mass to form an equilateral triangle of side 8m as shown. Determine the individual Torques and total moment of inertia of the system about axis XY. *formula for particles: I = mR^2 (where m=mass; R= radius) *formula for system: I total= summation of I = m1R1^2 + m2R2^2 + ... +mnRn^2 thank you so much for helping me understand our topic.
2. A shaft is supported on bearings A and B, 800 mm between centres. A 20 degrees straight tooth spur gear having 600 mm pitch diameter, is located 200 mm to the right of the left hand bearing A, and a 700 mm diameter pulley is mounted 250 mm towards the left of bearing B. The gear is driven by a pinion with a downward tangential force while the pulley drives a horizontal belt having 180 degrees angle of wrap. The pulley also serves as a flywheel and weighs 2000 N. The maximum belt tension is 3000 N and the tension ratio is 3: 1. Determine the maximum bending moment and the necessary shaft diameter if the allowable shear stress of the material is 40 MPa.
Please help to provide solution for the problem below. Thanks
A gear system shown in Figure 1 consists of gear B and C with radii of 80 mmand 200 mm, respectively. Gear B with a mass of 0.9 kg is free to rotate at pointA of the arm AO. The arm is free to rotate on the fixed axis O. Whereas, gear Cis fixed on the axles O in a way that it will never rotate. The arm has a mass of0.8 kg and a radius of gyration about O of 140 mm. Moreover, the arm AO hasa center of gravity located at point G.1.1. If the uniform torque of 4 Nm is applied to the arm OA, initially at rest in thehorizontal position, calculate the velocity of point A as it reaches the top point A’.1.2. Use the table method to calculate the angular speed of gear B, provided that thearm rotates at 5,118 rad/s.
