Single Block or Shoe Brake Question 1:
A single shoe block brake with 300 mm drum diameter is used to absorb a torque of 75 N – m with friction coefficient 0.35, applied force P is ________N
Answer (Detailed Solution Below) 688 - 692
Single Block or Shoe Brake Question 1 Detailed Solution
\(F_t =\frac{T}{r}=\frac{75\times10^{-3}}{150}=500\;N\)
\(F_t=\mu R_N\Rightarrow R_N=\frac{F_t}{\mu}=1428.6\;N\)
450 P = 200 RN + FT × 50 = 200 RN + 0.35 RN × 50 ____1)
450 P = 217.5 RN = 217.5×1428.6 ____2)
⇒ P = 690.49 N
Single Block or Shoe Brake Question 2:
A single shoe block brake with 300 mm drum diameter is used to absorb a torque of 75 N – m with friction coefficient 0.35, applied force P is ________N
Answer (Detailed Solution Below) 577 - 581
Single Block or Shoe Brake Question 2 Detailed Solution
Fr × 50 + P × 450 = N × 200
⇒ 0.35 × N × 50 + 450P = 200 N
⇒ 450P = 200N – 17.5N
Also; μN × ⋅150 = 75
⇒ P = 579.36 N
