We had a very smooth hand raising yesterday. This was the first hand raising I have planned and the walls went up easier than I expected (leaving some people with the bad feeling of being un-needed). We had 25 people on pikes and ten people just lifting with their hands and then the people on the ropes, stays and safety devices I had.

In planning the number of people needed to lift a wall by hand I took the weight of the 20' plate and half of the 10' posts as the weight to lift when the wall was laying down. My question is how do I figure out what the force needed to push the wall at various angles as the wall is going up? For example when the wall is half way up (45 degrees) what force is needed to hold it from coming back down? Is it simply one-half of the starting weight?

Know what I mean?
