How to calculate number of Bricks per ... - we civil engineers

Thickness of wall = full or 1 brick wall. No. of bricks = Volume of brickwork/ volume of 1 brick with mortar. Volume of 1 Brick with mortar = 0.240×0.120×0.080= 0.002304 m^3. Volume of brickwork = 1 m^2 x 0.230 m =0.230 m^3. ∴ No. of bricks in 1sq.m = 0.230/0.002304 = 99.826 ≊100 No's (without wastage) Consider the wastage percentage as ...

Rotational inertia (article) - Khan Academy

Rotational inertia is a property of any object which can be rotated. It is a scalar value which tells us how difficult it is to change the rotational velocity of the object around a given rotational axis. Rotational inertia plays a similar role in rotational mechanics to mass in linear mechanics. Indeed, the rotational inertia of an object ...
