SFD and BMD example 2

The video tutorial explains how to draw shear force and bending moment diagrams for a simply supported beam with a uniformly distributed load. It begins with an introduction to beam support types and distributed loads, followed by drawing a free body diagram and calculating reaction forces using static equilibrium equations. The tutorial then covers the calculation of shear force and bending moment along the beam, and concludes with plotting the diagrams and summarizing the process.

What type of load is applied on the beam in the problem?

• Uniformly distributed load

• Concentrated load

• Varying load

• Point load

What is the purpose of a free body diagram in this context?

• To calculate the weight of the beam

• To visualize the internal forces

• To identify reaction forces and supports

• To determine the material of the beam

How can a uniformly distributed load be simplified for reaction force calculations?

• By ignoring it

• By converting it to a varying load

• By replacing it with a point force at the centroid

• By doubling its value

What is the sum of forces in the X direction for the beam?

• Equal to the reaction at the pin support

• Equal to zero

• Equal to the sum of vertical forces

• Equal to the weight of the beam

What is the value of the reaction force BY?

• 30 Newtons

• 10 Newtons

• 20 Newtons

• 40 Newtons

What is the equation for the shear force V at any point X along the beam?

• V = 10X

• V = 40 - 20X

• V = 20 - 10X

• V = 30 - 5X

What is the equation for the bending moment M at any point X along the beam?

• M = 10X^2

• M = 40X - 20X^2

• M = 20X - 5X^2

• M = 30X - 10X^2

What shape does the bending moment diagram take?

• Exponential

• Linear

• Parabolic

• Circular

At what point along the beam is the maximum moment experienced?

• At the left support

• At the right support

• At the midpoint

• At the quarter point

What is the maximum moment value experienced in the beam?

• 30 Newton meters

• 20 Newton meters

• 10 Newton meters

• 40 Newton meters
