Offsets are measured with an accuracy of 1 in 40. If the point on the paper from both sources of error (due to angular and measurement errors) is not to exceed 0.05 cm on a scale of 1 cm = 20 m, the maximum length of offset should be limited to

Due to angular & linear sin45 = 0.7 then it is 1.414.

Cosec = 1/sin.
Than sin45 =.707.
Cosec = 1/.707 = 1.414.
Than sin45 =.707.
Cosec = 1/.707 = 1.414.

How come 1.414? Please explain the answer in detail.

L = s*r*error/1.414.
= 20*40*0.05/1.414 = 28.28 m.
= 20*40*0.05/1.414 = 28.28 m.

s*r/(40*1.414).
= (20*40)/56.56.
= 14.14 answer.
= (20*40)/56.56.
= 14.14 answer.

L = 0.05"40"20*14.14 = 28.28 m.
