Describe stepping method of chaining on sloping ground.
1. If A and B are the two points on sloping ground, for which horizontal distance is to be measured. 2. Unfold the chain. By touching handle to station A, stretch it up to maximum possible distance (without sag). 3. Suspend the plumb-bob from that stretched point and mark the point C on ground. 4. Now measure the distance L1 on chain by counting brass rings, brass talleys and links accurately. 5. Now, from point C, repeat steps 2,3and 4 up to station B and note down corresponding horizontal distances L2, L3 etc. 6. Thus total horizontal distance on sloping ground is calculated as d(AB) = L1+L2+L3 in meters.
