It is same as this one: http://www.engineeringtoolbox.com/forces-pipe-bends-d_968.html but i just change the bend direction

F is a force and R is a resultant force. http://www.engineeringtoolbox.com/forces-pipe-bends-d_968.html Im using this information but I change its direction

A bar of length 4m when used as simply supported beam and subjected to a uniform distribution load of 30kN/m over whole span, deflects 15 mm at the center. Determine the crippling loads when it is used as a column with following end conditions. a)both ends pin-jointed b)One end fixed and other...

Oh I didnt see that. Thank you so much... :D

R at B = 5.0625 R at A = 8.5kN-5.0625kN=3.4375kN x/0.9375=(0.5-x)/4.5625 x=15/176 but moment near x there i get different from both side: from A = 2.431kNm from B = 2.346kNm is there something wrong?

I found it. thanks for the hint

The original question: 2 steel rods and copper each of 20mm diameter together support a load of 20 kN. Find the stresses in the rod. Take E for steel and copper as 2.05 GN/m^2 and 1.10 GN/m^2. l=FL/AE for steel l=(20kN)(2m)/(0.0003141x3)(2.05 GN/m^2)=0.021 stress= lE/L=(0.021m)(2.05...

1. A 3.0-mm2 cross sectional area metal rod is stretched by 0.4 mm when a certain stretching force is applied to it. Another rod of the same length and metal but of a cross sectional of twice as large is stretched by the same amount of force. Calculate the stretching in the second wire. the...
