Question 1

What is the formula for calculating stress in a truss member?

  • Stress = P × A
  • Stress = P / A
  • Stress = A / P

💡 Hint: Remember: stress is how much force is spread over an area.

Question 2

True or False: Tension forces are considered negative in the sign convention.

  • True
  • False

💡 Hint: Think about our discussions on sign convention.

Challenge Problems

Push your limits with challenges.

Question 1

A truss member undergoes a total axial load of 1000 N and has a diameter of 10 cm. Calculate the stress in the member and must decide if it's safe based on a material strength of 150 N/cm².

💡 Hint: Apply the area formula first before finding the stress.

Question 2

A truss structure is subjected to external forces that cause moment reactions of 50Nm at the supports. If he member lengths are known, determine whether the truss is statically determinate by applying the criteria you've learned.

💡 Hint: Refer back to the definitions of internal and external determinacy.
