Verified Answer
A single block brake with a torque capacity of 250 Nm is shown in fig...
Nt = μNR
μNR = 250
N = 3571.42 N …(1)
Since net moment about hinge point is zero
P x 0.50 + 0.35 x 3571.42 x 0.05
= 3571.42 x 0.2
P = 1303.57 N …(2)
∴ Rx = 1250 N ...3
Ry = 3571.42 - 1303.57
= 2267.85 N …4
= 2589.52 N
