A horizontal conveyer belt moving at a uniform speed of 1.2 M/S transports material at the rate of 100 tonnes/hr. Belt is 200 M long and driven by a motor at 1200 rpm.
(a) Determine the load inertia referred to the motor shaft.
(b) Calculate the torque that motor should develop to accelerate the belt from standstill to full speed in 8 sec. Moment of inertia of the motor is 0.1 kg-.m2
Another very common basic mechanism is the "four-bar" (the ground is considered one of the
bars). The class has designed this demonstration four-bar with dimensions 2.2ft , 4.6ft
and 1.0ft

A shaft turning at a uniform speed carries two uniform discs A and B of masses 10kg and 8kg respectively. The centres of the mass of the discs are each 2.5mm from the axis of rotation. The radii to the centres of mass are at right angles. The shaft is carried in bearings C and D between A and B such that AC = 0.3m, AD = 0.9m and AB = 1.2m.
It is required to make dynamic loading on the bearings equal and a minimum for any given shaft speed by adding a mass at a radius 25mm in a plane E.
Determine:
The magnitude of the mass in plane E and its angular position relative to the mass in plane A
The distance of the plane E from plane A
The dynamic loading on each bearing when the mass in plane E has been attached and the shaft rotates at 200 rev/min. For the bearing loads in the…
