Explanation:
May I know how to calculate if a polycarbonate sheet rated to take 2 kg weight dropped from 1.5 meters can withstand a falling bullet exerting what is rated at 30 lb-ft impact force?
My calculation from your D*W above says that the sheet can withstand about 22 lb-ft force, is this correct or am I missing something? I have no data on the “bounce” or travel of the sheet surface, i just know that the sheet takes that load dropped from that height.
Hope it will help you please mark me as branlist
