SFD & BMD for a simply supported load

• SFD is a diagram that shows the variation of shear force along the length of a beam

• BMD is a diagram that shows the variation of bending moment along the length of a beam

• For a simply supported load, the SFD will be a straight line with a constant slope

• The BMD will be a parabolic curve with the maximum value at the center of the beam

• The SFD and BMD can be calculated using equations an

Different types of footings and their design

• Types of footings include spread footings, strip footings, and mat footings

• Spread footings are used for individual columns or walls

• Strip footings are used for a row of columns or walls

• Mat footings are used for large structures or where soil bearing capacity is low

• One-way footings distribute load in one direction, while two-way footings distribute load in two directions

• Design ...read more

Simply supported beam design involves determining the dimensions and reinforcement of a beam to support a given load.

• Calculate the maximum bending moment and shear force in the beam

• Determine the required dimensions of the beam based on the maximum bending moment and shear force

• Design the reinforcement, including the size and spacing of the bars

• Consider factors such as material properties, safety factors, and code requi...read more

The weight of steel per meter for a 25mm diameter

• The weight of steel per meter can be calculated using the formula: weight = (pi * diameter^2 * length) / 4

• The density of steel is approximately 7850 kg/m^3

• For a 25mm diameter steel rod, the weight per meter can be calculated as: weight = (3.14 * 0.025^2 * 1) * 7850 / 4 = 3.85 kg/m
