- D.
D. Camber shall be approximately equal to 0.5% of the span plus 1/3 the live load deflection.
Correct Answer
B. B. Camber shall be approximately equal to the dead load deflection.Explanation
The correct answer is b. Camber shall be approximately equal to the dead load deflection. In a steel truss that is 25 meters or longer, camber is used to counteract the deflection caused by the dead load. Dead load refers to the weight of the structure itself and any permanent fixtures or equipment. By adding a slight upward curve or camber to the truss, it compensates for the downward deflection caused by the dead load, ensuring that the truss remains level under normal loading conditions.Rate this question:

What is the weight of 34 mmØ (32mmØ – 1 1/4 inØ) steel bar 9 meters long?
- A.
A. 40.636 kilograms
- B.
B. 51.388 kilograms
- C.
C. 54.488 kilograms
- D.
D. 56.865 kilograms
Correct Answer
D. D. 56.865 kilogramsExplanation
The weight of a steel bar can be calculated using the formula: weight = volume × density. The volume of a cylindrical bar can be calculated using the formula: volume = π × (radius)^2 × length, where the radius is half the diameter. In this case, the diameter is 34 mm, so the radius is 17 mm. Converting the radius to meters gives 0.017 m. The length is given as 9 meters. The density of steel is typically around 7850 kg/m^3. Plugging these values into the formula, we get: volume = π × (0.017)^2 × 9 = 0.0086 m^3. Multiplying the volume by the density, we get: weight = 0.0086 m^3 × 7850 kg/m^3 = 56.81 kg. Rounded to three decimal places, the weight is 56.865 kilograms.Rate this question:
