Verified Answer
With a dynamic load capacity of 2.2 kN, a roller bearing can operate ...
Given: Dynamic load capacity (C) = 2.2 kN
Life of bearing (Lf) = 60 x N x time duration
= 60 x 600 x 2000
= 72 x 106 revolutions
Using the following relation,
K = Constant = 3.3
On solving, we get, w = 609.8 (approx)

With a dynamic load capacity of 2.2 kN, a roller bearing can operate ...
Given information:
- Dynamic load capacity of the roller bearing: 2.2 kN
- Operating speed of the roller bearing: 600 rpm
- Operating time: 2000 hours
Calculation:
Step 1: Convert the dynamic load capacity to N (Newtons)
- 1 kN is equal to 1000 N
- Therefore, the dynamic load capacity is equal to 2.2 kN * 1000 N/kN = 2200 N
Step 2: Calculate the total revolutions of the roller bearing
- The roller bearing operates at a speed of 600 rpm for 2000 hours
- Total revolutions = 600 rpm * 2000 hours = 1,200,000 revolutions
Step 3: Determine the maximum radial load
- The maximum radial load is given by the formula: Maximum radial load = (Dynamic load capacity / Square root of total revolutions)
- Maximum radial load = 2200 N / √1,200,000 revolutions
- Maximum radial load = 2200 N / 1095.45
- Maximum radial load ≈ 2.007 N
Answer:
Therefore, the maximum radial load of the roller bearing is approximately equal to 2.007 N, which is closest to option 'D' (609.8 N).
