Question: If a beam has a deflection limit of L/360, what is the maximum allowable deflection for a beam of length 4 m?

Options:

Correct Answer: 11.1 mm

Solution:

Maximum Allowable Deflection = L/360 = 4000 mm / 360 = 11.1 mm.

If a beam has a deflection limit of L/360, what is the maximum allowable deflection for a beam of length 4 m?

If a beam has a deflection limit of L/360, what is the maximum allowable deflection for a beam of length 4 m?

Step 1: Identify the length of the beam. In this case, the length (L) is 4 meters.
Step 2: Convert the length from meters to millimeters. Since 1 meter = 1000 millimeters, 4 meters = 4000 millimeters.
Step 3: Use the deflection limit formula, which is L/360. This means we will divide the length of the beam in millimeters by 360.
Step 4: Calculate the maximum allowable deflection by dividing 4000 mm by 360.
Step 5: Perform the division: 4000 mm / 360 = 11.1 mm.
Step 6: Conclude that the maximum allowable deflection for the beam is 11.1 mm.

Deflection Limit – The maximum allowable deflection of a beam is often expressed as a fraction of its length, in this case, L/360.
Beam Length – Understanding the length of the beam is crucial for calculating the maximum allowable deflection.
Unit Conversion – Converting units from meters to millimeters is necessary to match the units used in the deflection calculation.
