Aim:

To find Deflection of a beam problem

Explanation Explanation attached below file_12Aug22-2

Result: For EI=20x10^6Nm^2 is y=0.05327mm

For EI=25x10^6Nm^2 is y=0.0034

For y=5mm is EI=26.041x10^6Nm^2

S.No:5

Aim:

To Design channel purlin, considering sag rod at mid span for the roof truss having following data

• Span of truss : 20 m
• Spacing of Truss : 4 m c/c

• Roof slope : 20 degrees
• Spacing of purlin : 2 m
• Wind suction : 1 kN/m²
• Live Load : 0.75 kN/m² ,Dead Load 1.4 kN/m²

Result: Hence proved.
