a) Determine the gross moment of Inertia, in x10 mm ² Determine the cracking moment, in KN.m c.) betermine the live load that the becum can carry if it has a simple span of 10 meters in kn.m.

please just solve the second part

A cast iron beam 12m long and supported as shown carries a uniformly distributed load of intensity wo, N/m, (including its own weight). The allowable stresses are ??? ≤ 25 MPa and ??? ≤ 90 MPa. Determine the maximum safe value of wo, in N/m, if x= 1.2m.

Please explain the steps with the solution

I need the answer as soon as possible

YIELD AND MOVE tO GE THERA DISTAHCE OF O.5mm A 25m STEEL ROD WITH A CRO6S-SECTIONAL ÅREA OF 1250mm? IS SECURED BETWEEH RIGID SUPPORTS AT BOTH ENDS. IF THERE IS NO STRESS AT A TEMPERATURE OF 20°C, E- 200000 MPa. a. COMPUTE THE STRESS WHEN THE TEMPERATURE DROPS TO O°C, IF IT HAS A COEFFICIENT OF THERMAL EXPANSION OF 0. 0000||7 m/m°C. b COMPUTE THE STRAIN OF THHE ROD IF THE ROD SUPPORTS YIELD AND MOVE TOGETHER A DISTANCE OF O.5mm AS TEMPERATURE DROPS. C. COMPUTE THE STRESS IH THE ROD IF THE SUPPORTS AS THE TEMPERATURE DROPS. CS Scanned with CamScanner

I will rate immediately, thank you!

A circular aluminum alloy [E = 70 GPa; a = 22.5 x 10-6/°C; v = 0.33] pipe has an outside diameter of 220 mm, a wall thickness of 15 mm, and a length of 4.0 m. The pipe supports a compressive load of 650 kN. After the temperature of the pipe drops 41°C, determine: (a) the axial deformation of the pipe. (b) the change in diameter of the pipe. Answer: (a) ō = i mm AD = i mm

A circular aluminum alloy [E = 70 GPa; α = 22.5 × 10–6/°C; ν = 0.33] pipe has an outside diameter of 265 mm, a wall thickness of 11 mm, and a length of 4.6 m.  The pipe supports a compressive load of 640 kN.  After the temperature of the pipe drops 35°C, determine:(a) the axial deformation of the pipe.(b) the change in diameter of the pipe.

2. Axial loads are applied to the compound rod that is composed of an aluminum segment rigidly connected between steel and bronze segments. What is the stress in each material given that P = 10 kN?
