Question

The formula for calculating the total load supported by a lintel in which total load is given by the expression 0.44 L^2 x t x W /100 is derived by assuming an angle of spread of __________

(a) 15°

(b) 30°

(c) 45°

(d) 60°

Answer 1

The correct option is (b) 30°

For explanation I would say: The total supported by a lintel is given by the expression 0.44 L^2 x t x W /100. This formula is derived assuming an angle of spread of 30° and that the lintel supports a load of the shape of an equilateral triangle having side equal to L meters.
