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°I had been asked this question in exam.I need to ask this question from Load Bearing Walls topic in section Load Bearing Walls of Construction & Building Materials

Answer»

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.
