For the initial consideration of design of a swing with one bay, single post swing frame with the loading conditions as shown below you are required to determine distribution of shear force and bending moment due to bending across the central beam. Length of central beam = 4.0 m Weight of the beam = 300 N/m distributed uniformly across the beam and are the point loads due to weight of the rider which is assumed to be distributed equally between the support chains. It is assumed that the weight of the rider does not exceed 1000 N (about 100 kg) All length measurements are in m. Clearly, sketch the shear force and bending moment diagrams for the situation considered. From the diagrams produced, state the maximum SF and BM and clearly indicate the positions where they occur. Task 2 Select a standard rolled steel I-section for the simply supported beam in task 1 above. Select an appropriate factor of safety and material strength. Include references for all sources of information employed. So with the max SF being 1100 and the max bending moment being 1400 how do you calculate max stress to then solve the elastic section modulus?
Task 1
For the initial consideration of design of a swing with one bay, single post swing frame with the loading conditions as shown below you are required to determine distribution of shear force and bending moment due to bending across the central beam.
Length of central beam = 4.0 m
Weight of the beam = 300 N/m distributed uniformly across the beam
and are the point loads due to weight of the rider which is assumed to be distributed equally between the support chains.
It is assumed that the weight of the rider does not exceed 1000 N (about 100 kg)
All length measurements are in m.
Clearly, sketch the shear force and bending moment diagrams for the situation considered.
From the diagrams produced, state the maximum SF and BM and clearly indicate the positions where they occur.
Task 2
Select a standard rolled steel I-section for the simply supported beam in task 1 above. Select an appropriate factor of safety and material strength. Include references for all sources of information employed.
So with the max SF being 1100 and the max bending moment being 1400 how do you calculate max stress to then solve the elastic section modulus?
