How are you doing guys? I am new in doing calculation for machine. I am currently have a task to provide sample calculation on how to determine the thickness of plate to be used in a machine like mobile crane, tower crane, boom lift, building maintenance equipment. Need to know the formulas that needs to be used in order for me to come up with a correct thickness of plate knowing that there are some attachments in the plate (body) like motor, shaft and so on. Hope you guys can help me with this. Thank you in advance!
