ok so if a crane lifts a 500 kg mass to a height of 20m in 40 seconds what is the work done by the crane, the output power at the cranes hook ad the input power to the electrical motor if the combined efficiency is 0.8?alsoIf a 50kg mass is raised vertically through a height of 40m in 20s what is its energy in the raised position and what power was developed in raising the load?Thankyou in advance
Depends what ammunition you're talking aboutIf you're talking about .223 it will be fine since the rounds do not exert enough pressure to bend the feed lipsIf you're talking about 6.8 get a high quality mag, I left mine loaded in a c products and it destroyed the lips to the point where I can't use itI had to spend 43 on a pri magazine and I haven't had any problems with them, no bends, no dents, nothing.
why does this need to change if they are safe whre they are ? the loading out of its box into a stell shell?
