A shaft has three eccentrics of mass 1kg each. The central plane of the eccentrics is 50 mm apart. The distances of the centers from the axis of rotation are 20 mm, 30 mm, and 20 mm and their angular positions are 120 degree apart. Find the amount of out-of-balance force and couple at 600 rpm. If the shaft is balances by adding two masses at a radius of 70 mm and at a distance of 100 mm from the central plane of the middle eccentrics, find the amount of masses and their angular positions. (Use graphical method for solution)
Two gears (A and B) are in mesh (they are interlocked) and both spin around their centers of gravity.   Gear A has a radius of .8 ft and is experinceing a 10 ft-lb CW moment   Gear B has a radius of 1.2 ft   If gear A is initially moving at 60 rpm CW, determine how long it will take for gear B to be rotating at 300 rpm CCW
Inside a machine, two gears, A and B, HINGED at their centers, are meshed with each other such that gear A transmits torque and speed to gear B. Gear A has a mass mA=2 kg, radius rA=175 mm, and radius of gyration kA=150 mm. Gear B has a mass B=5 kg, radius rB=525 mm, and radius of gyration kB=400 mm. From rest, a counter-clockwise couple M of constant magnitude 6 Nm is applied to Gear A. Which of the following is closest to the magnitude of the angular acceleration of gear B, in radians per square seconds (rad/s2)?3.0044.814.9445.6
