1. You are tasked to design a shaft for power transmission through a belt and pully at its right side. The shaft issupported 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 forselecting the correct bearings from the catalog)Tip: Journal bearing can only support lateral (radial) force, like By in this problem, while Thrust bearings cansupport 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 mechanicalfailure. Find the resultant internal loadings acting on the cross-section at C. If the shaft diameter at this section is0.3 mm, what are the average normal and shear stresses at this section?700 N/mIIIIC|--1m+1 m +1 m+15m 2mD1 kN

O: A shaft is to be designed for a linkage of a windshield wiper mechanism for a truck as shown in Tigure below. A 20-N force is applied to lever 1 (I'1) by an adjacent link. The reaction force (F2) on lever 2 is transmitted to another link. Requirement: Select suitable bearings points A & D.
Q: Figure (1) shows a schematic drawing of a countershaft which is part of the conveyor system and supports two belt pulleys (A & B). The belt tensions are parallel for pulley B and inclincd with angle 45° for pulley A. The pulley A reccives a power from a motor and then delivers to conveyor belt through pulley B. All dimensions are in mm. Required: Design the shaft as shown in figure (1) at points O, A, B & E.

Shown below is a figure of a landing gear configuration on the VS and VD planes (for landing gear the directions V, D, and S are often used instead of x, y and z) This gear unit is assumed to represent one side of the main gear on a tricycle type of the landing gear system. The loading assumed corresponds to a condition of nose wheel up or tail down. The design load on the wheel is vertical and it s magnitude for this problem is 15,000 lbf. Determine the reactions at F, H, and G. The fittings at F and H are pinned and therefore cannot transmit any bending moments. The fitting at G is also a pinned fitting.

Below question is from machine design. Please solve asap. You have to select bearings which are used to support a shaft, bearings are mounted at each end of shaft and 1.20 metre apart. A 600 mm diameter pulley 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 400 mm diameter is 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 angle of contact for both pulleys is 180º and .Allowing working stress of shaft depends on the material you have selected for the shaft. Select the type of bearing mounted on both ends of shaft (either ball or roller bearing type and also elaborate the scenario for the selection of bearing).The Reliability Factor for Bearing may vary from 92% till 96%
