Test: Influence Lines For Beams - Question 1

While writing influence line equations, left most point is always considered as origin and following sign convention is followed.

Q. If on ILD analysis peak force comes out to be 2 KN, then what will be the peak force if loading is 2KN?

Detailed Solution for Test: Influence Lines For Beams - Question 1

Answer: d
Explanation: Peak force will be load multiplied by earlier peak load i.e. 2*2.

Test: Influence Lines For Beams - Question 2

Following figure is for Q2-Q7.

AC= 1m, CB =3 m
C is just an arbitrary point. A is pin support and B is a roller type support.

Q. What will be the equation of ILD of shear force at point C for AC part?

Detailed Solution for Test: Influence Lines For Beams - Question 3

Answer: c
Explanation: Just assume force at any point between AC and conserve moment about point A.

Test: Influence Lines For Beams - Question 4

Following figure is for Q2-Q7.
AC= 1m, CB =3 m
C is just an arbitrary point. A is pin support and B is a roller type support.

Q. If we have to apply a concentrated load in the above shown beam, such that shear at C becomes max. , where should we apply that load?

Detailed Solution for Test: Influence Lines For Beams - Question 4

Answer: c
Explanation: If we draw ILD according to the above given equations, we will see that peak of ILD comes at point C

Test: Influence Lines For Beams - Question 5

Following figure is for Q2-Q7.
AC= 1m, CB =3 m
C is just an arbitrary point. A is pin support and B is a roller type support.

Q. If a concentrated load of 50KN is applied at point C, then what will be the shear developed at point C?

Detailed Solution for Test: Influence Lines For Beams - Question 5

Answer: c
Explanation: Position of ILD at point C is 0.75 (peak). So, shear developed will be 0.75 multiplied by 50KN.

Test: Influence Lines For Beams - Question 6

Following figure is for Q2-Q7.
AC= 1m, CB =3 m
C is just an arbitrary point. A is pin support and B is a roller type support.

Q. What will be the shear developed at point C if a uniform load of 10KN/m is applied between point B and C?

Detailed Solution for Test: Influence Lines For Beams - Question 6

Answer: b
Explanation: In case of uniform load, area of ILD curve multiplied by uniform load gives the shear.

Test: Influence Lines For Beams - Question 7

Following figure is for Q2-Q7.
AC= 1m, CB =3 m
C is just an arbitrary point. A is pin support and B is a roller type support.

Q. If both, a load of 50KN at point C and a uniform load of 10KN/m between CB acts, then what will be the shear generated at point C?

Detailed Solution for Test: Influence Lines For Beams - Question 7

Answer: a
Explanation: Net shear generated will be the sum of individually generated shear which has been already calculated earlier.
