What is the mass of 5m3 of cement of density 3000kg/m3 ?
Density = Mass/Volume Mass = Density x Volume Mass = 3000Kg/m3×5m3 = 15000 Kgs.
The breaking stress of a material is 108N/m, density of material is 3000kg/m3 . Find the greatest length of wire that could hang vertically without breaking. (Pause the video and solve without looking at the solution).
