Which one of the following is correct?An intermediate vertical stiffen...
Given:
An intermediate vertical stiffener connected to the web is designed to withstand a shearing force of not less than where t is web thickness in mm and h is the outstand of stiffener in mm.
To find:
The correct formula for calculating the shearing force.
Solution:
The correct formula for calculating the shearing force is given by option 'D', i.e., 125t^2/h.
Let's understand why this formula is correct.
Explanation:
The shearing force on the stiffener can be calculated using the formula:
Shearing Force = Shear stress × Area
The shear stress on the stiffener is given by:
Shear stress = Shear force / Area
The area of the stiffener can be calculated as the product of the thickness of the web (t) and the outstand of the stiffener (h). Therefore, the area is given by:
Area = t × h
Substituting the value of the area in the formula for shear stress, we get:
Shear stress = Shear force / (t × h)
Now, we need to calculate the minimum shearing force that the stiffener can withstand. According to the given information, the shearing force should be not less than a certain value.
The formula given in option 'D' is 125t^2/h. By comparing this formula with the formula for shear stress, we can see that it is the square of the thickness (t^2) multiplied by a constant factor (125) and divided by the outstand of the stiffener (h). Therefore, this formula represents the shearing force.
Hence, the correct formula for calculating the shearing force is 125t^2/h, which is given in option 'D'.
