Concept explainers

Slope and Deflection

The slope in a deflected beam is described as an angle in radians made by the tangent of the section with the original axis of the beam. The deflection at any point on the axis of the beam is defined as the lateral displacement of the point before and after loading.

Question

**Problem Statement:**

A steel shaft rotating at 600 rpm is supported by two bearings as shown. The parameters are given as follows:
- Modulus of Elasticity, \( E = 30 \) Msi
- Diameter, \( d = 1.0 \) inch
- Distance from left bearing to load, \( L_1 = 24.0 \) inches
- Total length of the shaft, \( L = 42 \) inches
- Applied load, \( W_1 = 50 \) lb

Neglect the weight of the shaft.

Question: "The design is acceptable." Is this statement true or false? Show details.

**Diagram Explanation:**

The diagram included consists of:
- A horizontal shaft with two bearings, depicted as crossed rectangles.
- A force, \( W_1 \), is applied at a point on the shaft.
- Key lengths are marked:
- \( L_1 \) is the distance from the leftmost bearing to the point where the load \( W_1 \) is applied.
- \( L \) is the total length of the shaft.
- The diameter \( d \) of the shaft is noted and marked with a double-headed arrow perpendicular to the shaft.

Understanding whether the design is acceptable involves calculating stresses and deflections in the shaft and comparing them to allowable values determined by design standards.

In the design in the figure, a force of Fn=45992 N acts in the vertical plane on a machine element with a diameter of D=200 mm on the shaft resting on the A and B bearings. If the angle made by this force with the horizontal is b=40o, find the life of the 6210 coded Deep Ball bearing to be used in the B bearing, in hours. Number of revolutions = 30 rpm. 1-) The diameter of the machine element on which the force acts will be taken into account in the calculation of bearing forces (That is, it will be assumed that the Fn force AFFECTS THE GROUND shown in the figure, NOT the axis of the shaft). 2-) Pi number will be taken as 3.14.
