Answer #1

solution:-

  • upon changing area(A) and young's modulus (E) it will not lead to change in shear force diagram and Bending moment diagram.
  1. Because shear force diagram is a diagram that represents the variation of shear force along the length of beam and only depends on the loading and doesn't depend on the area, young's modulus of the beam.
  2. and bending moment diagram is variation of moment along the length of the beam and it also doesn't depend on the area and Young's modulus of the beam.
  • FOR EXAMPLE
  • IF you take a simply supported beam with uniformly distributed load.

Q3: Bending moment and shear force diagrams were plotted for a cantilever beam of span 10 m when subjected to a uniformly distributed load of magnitude ‘w’ kN/m over the entire span, two concentrated loads ‘2w’ kN at a distance 3 m from the free end and ‘3.5w’ kN at a distance 4.5 m from the free end respectively. It was observed that the value for maximum bending moment acting on the beam is equal to (-175 kNm). Suggest a...

A ruler is accurate when the temperature is 26.7 °C. When the temperature drops to -12.3 °C, the ruler shrinks and no longer measures distances accurately. However, the ruler can be made to read correctly if a force of magnitude 1.72 x 103 N is applied to each end so as to stretch it back to its original length. The ruler has a cross-sectional area of 1.39 x 10-5 m2, and it is made from a material whose coefficient of...
So, why can a properly executed karate kick break a concrete block without fracturing bones [16]?...
So, why can a properly executed karate kick break a concrete block without fracturing bones [16]? First, bone is a very strong material. Its ultimate compressive strength is approximately 40 times larger than concrete. Second, contact is made with the edge of the foot. This concentrates the force into a small area of the target and reduces the likelihood of bending a bone to the point of fracture. Third, the collision with the target is essentially inelastic and extends over...
