Question

The 450-kg uniform I-beam supports the load of 220 kg as shown. Determine the reactions at the supports. (2850N) R = ? 5.6 m R = ? # 2.4 m K lan (t 220 kg​

Answer 1

Answer:

tension in the wire is

F=4.0x3.1πN

TheareaofcrosssectionisA=pir^2=pix(2.0xx10^-2m)^2=4.0pixx10^-6m^2Thus,thetensi≤stressdeveloped.=F/A=(4.0xx3.1pi)/(4.0pixx10^-6)Nm^-2=3.1xx10^6Nm^-2`
