The brake shown in the figure has a coefficient of friction of 0.30, a face width of 2 in, and a limiting shoe lining pressure of 150 psi. Find the limiting actuating force F and the torque capacity.
Answer to relevant QuestionsRefer to the symmetrical pivoted external brake shoe of Fig. 16–12 and Eq. (16–15). Suppose the pressure distribution was uniform, that is, the pressure p is independent of θ. What would the pivot distance a′ ...The brake shown in the figure has a coefficient of friction of 0.30 and is to operate using a maximum force F of 400 N. If the band width is 50 mm, find the band tensions and the braking torqueShow that for the caliper brake the T / (f F D) versus d / D plots are the same as Eqs. (b) and (c) of Sec. 16–5.For the conditions of Prob. 16–27, make a plot of the equivalent inertia Ie as ordinate and the stepdown ratio n as abscissa in the range 1 ≤ n ≤ 10. How does the minimum inertia compare to the single-step ...Take the drive of Prob. 17–5 and double the belt width. Compare Fc, Fi , F1a, F2, Ha, nf s , and dip.
