A shaft is supported by two bearings placed1.2 m apart. A pulley of diameter Dc=0. 675 meter is mounted at a distance of 300 mm to the right of left hand bearing and this drives a pulley directly below it with the help of belt having maximum tension of 2.25 kN. Another pulley of diameter Dd= 0.575 meteris placed 200 mm to the left of right hand bearing and is driven with the help of electric motor and belt, which is placed horizontally to the right.

The figure shows the rear rotating axle of a 4-wheel wagon with the same FRONT AXLE design and REAR AXLE design. The wagon moves at a constant speed and the diameter of the wheels carrying the axle is D=512 mm and the circumferential speed=3.1 m/s. Due to the load (m) on the wagon, a force of 16574 Newtons acts in the vertical direction. ALSO, a horizontal force of 21% of the vertical load acts on the wagon laterally (horizontally) in bends. It is planned that the bearings of the axle will be bearing 6008 deep groove ball bearings. Calculate the life of bearing A in hours.The radial effect of lateral loads will not be taken into account in the bearing force calculation. Fo.Fa/Co = 1.38 Pi=3.14

1. You are tasked to design a shaft for power transmission through a belt and pully at its right side. The shaft is supported by a thrust bearing at A and a journal bearing at B. a) Determine the support forces the bearings have to "bear". (In machine design, this step is necessary for selecting the correct bearings from the catalog) Tip: Journal bearing can only support lateral (radial) force, like By in this problem, while Thrust bearings can support axial and lateral forces, like A, and A, in this case. b) Upon inspection of the shaft, you decide that the cross-section C needs to be evaluated to avoid mechanical failure. Find the resultant internal loadings acting on the cross-section at C. If the shaft diameter at this section is 0.3 mm, what are the average normal and shear stresses at this section? 700 N/m IIII C |--1m+1 m +1 m+15m 2m D 1 kN

The figure below depicts the tire, axle, and gear of a large tractor. The entire structure is in mechanical equilibrium. Bearings support the rotating axle at points A and C attached to the tractor's frame. A force FD = 5000 lb is applied in the -z direction at point G of a gear with a 3-in radius. The force W = 1000 lb in the +z direction represents a normal force resulting from the weight of the tractor. The force Q acting in the +x direction, represents the traction force between the tire and the ground. The wheel, axle, and gear assembly weigh 150 lb with center of gravity at point D, which lies on the y axis with coordinate yp = -18 in. Points A, C, D (not seen in the figure), and E lie in the yz plane. Point G lies in the xy plane.

In the design in the figure, a force of Fn=1912 N in the vertical plane and a torque of Md=916 Ncm in the clockwise direction of rotation act on a machine element with a diameter of D=200 mm on the shaft resting on the A and B bearings. If the angle of the force with the horizontal is b=49o, how many Newtons is the resultant radial force to be considered in the bearing calculation of the bearing A? 1-) The diameter of the machine element on which the force acts will not be taken into account in the calculation of the bearing forces (ie, it will be assumed that the Fn force acts on the axis of the shaft). 2-) Pi number will be taken as 3.14.
