Combined Loading

Any functioning component, such as machine parts, structural members, pressure vessels, and so on, are all under the influence of more than one force. When anybody is under the influence of more than one force such as shear forces, bending moments, axial forces, torsion, and so on, then such body is said to be under combined loading. A very practical example of combined loading is the crankshaft of an internal combustion engine (IC engine). The crankshaft of the IC engine is under high rpm, which is caused due to the torsional forces. Due to the presence of piston, counterbalances, and internal imbalances, the crankshaft experiences lateral forces and due to the rise in temperature, the crankshaft undergoes thermal expansion, which pulls the crankshaft along the axial direction and lateral direction. The presence of unbalanced loads along the periphery of the crankshaft also induces a bending moment.

Question

can please help me with these questions

A steel beam, of lengths a= 4 m and b=4 m and
a hollow box cross section, is supported by a
hinge support A and roller support B, see Figure
Q.1. The width and height of the cross section
are 200 mm and 300 mm, respectively, and the
wall thickness of the cross section is 5 mm. The
beam is under a distributed load of the intensity
that linearly varies from q = 0 kN/m to q = 4.2
kN/m for AB span; and is constant with q = 4.2
kN/m for BC span. The Young's modulus of steel
is 200 GPa.

Partial Question 9 Which choices are correct explanations about the scanning electron microscope (SEM)? (Select all that apply.) Visible light is the main light source. The microscope can investigate non conductive samples as good as the conductive ones. Samples need to be polished. The condensed beam does not pass through the specimen, but is reflected from a surface of the specimen and was collected to obtain the picture. Useful resolution range is much wider than the optical microscopes.
