Chapter 21, Problem 1SA
What is the purpose of an IVR?
Expert Solution & Answer
To determine
The purpose of the IVR.
Answer to Problem 1SA
The two core purposes of the IVR are as follows:
- Voltage stabilisation.
- Reduce radio interference.
Explanation of Solution
The IVR stands for Instrument Voltage Regulator. The two core purposes of the IVR are as follows:
- The IVR stabilizes and limits the voltage to gauges. This leads to accurate gauge reading.
- A radio choke included in the IVR clears the radio interference caused due to the pulsating output of the IVR.
Conclusion:
Thus, the two core purposes of the IVR are as follows:
- Voltage stabilization.
- Reduce radio interference.

PROBLEM 1.52
Each of the two vertical links CF connecting the two horizontal
members AD and EG has a 10 × 40-mm uniform rectangular cross
section and is made of a steel with an ultimate strength in tension of
400 MPa, while each of the pins at C and F has a 20-mm diameter and
are made of a steel with an ultimate strength in shear of 150 MPa.
Determine the overall factor of safety for the links CF and the pins
connecting them to the horizontal members.

PROBLEM 1.51
Each of the steel links AB and CD is connected to a support and to
member BCE by 25-mm-diameter steel pins acting in single shear.
Knowing that the ultimate shearing stress is 210 MPa for the steel
used in the pins and that the ultimate normal stress is 490 MPa for
the steel used in the links, determine the allowable load P if an
overall factor of safety of 3.0 is desired. (Note that the links are not
reinforced around the pin holes.)

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.
