For the half deflection method which of the following stands correct, where G, R and S has the usual meaning?

A

G = RSRS\frac { \mathrm { RS } } { \mathrm { R } - \mathrm { S } }

B

R =

C

S = RGR+G\frac { \mathrm { RG } } { \mathrm { R } + \mathrm { G } }

D

All of these

Answer

All of these

Explanation

Solution

G = RSRS\frac { \mathrm { RS } } { \mathrm { R } - \mathrm { S } }

= =

1S1R=1G\frac { 1 } { S } - \frac { 1 } { R } = \frac { 1 } { G }

R =

S =
