if my stress is 160 mpa and my gpa is 71 am i correct in strain = stress/e 160*10 to the power of 6/71*10 to the power of 9 =2.25 *10 to the power -2

Homework Statement hi guys i have a sheet of i have the W,L and T a force and also the elastic modules etc now my issue is i need to find the strain i have the stress etc but the is no extension figure given i have the usual strain equation e=x/l can anyone point me in the right direction in...

Thanks what is the formula for this?

i am trying to find the pure bending moment of this beam 1. Homework Statement simply supported solid beam 3m long W=100mm D=200mm with a UDL of 2tonnes/m and a point load in the centre of 200N Homework Equations is the pure bending moment at the peak of the bending moment diagram i have...

so would that be considered the pure bending moment if it included the point load? and including the point load would it be 22,347N? the reason i ask this is i have found some notes that will help me a whole bunch if i correctly find the pure bending moment. My next question is there is no...

is the shear force in the centre of the beam calculated by calculating the area of the triangle so 29,530N*1.5m/2= 22,147N

therefore it should be 29,530N is that correct?

how do I calculate thart?

please ignore that

so very sorry please forgive me I am getting confused again I have tried that many calcs trying to get this I am in a bit of a muddle 1.5m at 2 tonnes/m = 3 tonnes 3 tonnes converted to KN =29.892049152000002KN so 29.9KN from x=o to x=1.5 not forgetting the point load in the centre of 200N am...

29.5KN

29.5*1.5/2=22.125KN

so combined reactions would be 59.0399KN 59.0399/2=29.51995 so a raction of 29.5 KN

using consistent units? KN?

W= 6 tones so the reaction forces at each support would be 3 tonnes an for the point load W=200N as this is central the reaction forces at the supports would be 100N is this the one you mean steamking?
