Given data:
Diameter of the journal = 30 mm
Maximum end reaction = 2500 N
Allowable bearing pressure = 5 N/mm2
To find:
Length of the sliding bearing
Formula:
Bearing pressure = (Force on the bearing) / (Area of the bearing)
Calculation:
1. Calculate the area of the bearing:
Area of the bearing = π × (Diameter of the journal) × (Length of the bearing)
⇒ Area of the bearing = π × (30 mm) × (Length of the bearing)
2. Substitute the given values:
5 N/mm2 = (2500 N) / [π × (30 mm) × (Length of the bearing)]
3. Solve for the length of the bearing:
Length of the bearing = (2500 N) / [5 N/mm2 × π × (30 mm)]
⇒ Length of the bearing = (2500 N) / [5 N/mm2 × 3.14 × 30 mm]
⇒ Length of the bearing ≈ 16.67 mm
Therefore, the length of the sliding bearing for an allowable bearing pressure of 5 N/mm2 is approximately 16.67 mm.
