Question
Chapter 26, Problem 1RQ
To determine
The advantage of the point to point method of connecting the circuit components.
Expert Solution & Answer
Explanation of Solution
The point to point method is the method which is used to install the circuit components in the control circuit. The wire numbers are given in this method to the wires of the control circuit but not the load circuit. Where all the components are located in the motor circuit and are represented by the dashed lines.
The advantages of the point to point method is that this method is used to show the actual position of the wire of the component that reduces the wastage of the wire.
The component that are insider the control circuit and the outside the circuit can easily be distinguished.
Also, the point to point method show the designation of the wires and the tags.
In this method the troubleshooting and the servicing is easy as the wire numbers are given to the wire, also the components are easy to be identified as the wires are tagged and labelled.
Thus, the advantage of the point to point method is described.

The vertical shaft shown in Figure P12-37 is driven at a speed of 600 rpm with 4.0 hp entering through the bevel gear. Each of the two chain sprockets delivers 2.0 hp to the side to drive mixer blades in a chemical reactor vessel. The bevel gear has a diametral pitch of 5, a pitch diameter of 9.000 in, a face width of 1.31 in, and a pressure angle of 20°. Use SAE 4140 OQT 1000 steel for the shaft. See Chapter 10 for the methods for computing the forces on the bevel gear.

The double-reduction, helical gear reducer shown in Figure P12-35 transmits 5.0 hp. Shaft 1 is the input, rotating at 1800 rpm and receiving power directly from an electric motor through a flexible coupling. Shaft 2 rotates at 900 rpm. Shaft 3 is the output, rotating at 300 rpm. A chain sprocket is mounted on the output shaft as shown and delivers the power upward. The data for the gears are given in Table 12-5. Each gear has a 1412° normal pressure angle and a 45° helix angle. The combinations of left- and right-hand helixes are arranged so that the axial forces oppose each other on shaft 2 as shown. Use SAE 4140 OQT 1200 for the shafts.
