A differential band brake is shown in the figure. The width and the thickness of the steel band are 100 mm and 3 mm, respectively and the maximum tensile stress in the band is 50 N/mm2. The coefficient of friction between the friction lining and the brake drum is 0.25.
What will be the tensions in the band?
  • a)
    12 kN and 4210 N
  • b)
    10 kN and 3509 N
  • c)
    19 kN and 6656 N
  • d)
    15 kN and 5263 N
Correct answer is option 'D'. Can you explain this answer?

We have, b = 100 mm, t = 3 mm, ∝ = 0.25,σt = 50 N/mm2, r = 0.3 m and ፀ= 240° = 240 x π / 180 = 1.334 π rad
The maximum tension in the band is,
T1 = σt bt = 50 x 100 x 3 = 15000 N = 15 kN
Minimum tension in the band is,
