Shown in the figure is a single block brake. The intensity of pressure between the block and brake drum is 1.5 N/mm2 . The dimension of block is 40 mm X 80 mm. The coefficient of friction is 0.25. What is the value of hinge pin reaction for clockwise rotation of the drum?
  • a)
    1860 N
  • b)
    3175.5 N
  • c)
    2940 N
  • d)
    Cannot be calculated from given data
Correct answer is option 'B'. Can you explain this answer?

Normal reaction,N = P(lw)
= 1.5 x 40 x 80 = 4800 N
Taking moment about hinge pin,
(μN) x (70) + P x (600) - N(250) = 0
0.25 x 4800 x 70 + P x 600 - (4800) x 250 = 0
P = 1860 N
Rx = μN = 0.25 x 4800 = 1200 N
Ry = N - P = 4800 - 1860 = 2940 N
