I am an engineer working on the design of a concrete ground floor slab. the slab in question could be subject to the impact loading of a 32 metric tonne mass falling from a heigh of 1.5m. i am trying to convert this into a point load in kN. could some kind soul please review my calculations below: velocity = square root of 2gh = 5.4222 m/s kinetic energy = 0.5mv^2 = 0.5 x 32000 x 5.4222^2 = 470400 joules...... as joules is a work force it converts to kNm. can it be converted to a kN point load??
