Question

Which of the following statements is true about the relationships between load w, shear force V, and bending moment M? The load intensity W at any section is equal to the rate of change of shear force V per unit length The shear force at a section is equal to the shear force at the previous section plus the total load between the two sections The slope of the moment diagram at any section equals the value of the shear force V at that section The moment at a section is equal to the moment at the previous section plus the area under the shear diagram between the two sections O All of the above

Answer 1

Answer:All are correct

Step-by-step explanation:

All the given option is correct as the relation between load w,shear force V, and bending moment M is

`\frac{\mathrm{d} M}{\mathrm{d} x}=-V`

`\frac{\mathrm{d} V}{\mathrm{d} x}=-w`

and
`\frac{\mathrm{d^2} M}{\mathrm{d} x^2}=w`

Also the Shear at a section is equal to previous section plus the total load between two required section .

Same is true for Bending Moment
