stbilized steel
It creates an iron bar with wire coiled around it. It can also create a spring, provided it stays in the same place for long enough so that it holds it's shape.
when length of reinforcing bar is small and we have to provide longer reinforcement in that case the second bar is provided with proper overlapping with the first bar this overlapping is known as lap length. the straight length of shall not be less than 12mm dia and 200mm length.
I think the bar along the span is main bar
Relief holes are provided for easy handling of sine bar and for reducing the weight of the sine bar.
To reduce the weight
distance between the centre of two parallel cylinderin the sine bar
sine bar is used to measure the angles of given work pieces

What is the angle of a workpiece if a 3.2003 gage block stack is used with a 10 sine bar?
stbilized steel
its a type of sine bar . it is used in metrology lab .from this equipment we can find tapered angle of a conical spcimen
1degree
Machinist Hand Book
Yes
1 it can not used when the angle more than 45 degrees.....
