A friction clutch in the reel exerts a restraining torque of 1.3 Nm if a fish pulls on the line. The fisherman gets a bite, and the reel begins to spin with an angular acceleration of 68 rad/s2 (a) What is the force of the fish on the line? N (b) How much line unwinds in 0.45 s? cm

The coefficient of static friction between the cylinder and all surfaces is 0.530. Find, in terms of w, the maximum force that can be applied without causing the cylinder to rotate. (Hint: When the cylinder is on the verge of slipping, both friction forces are at their maximum values) w Figure P8.74 9. [-/14 Points! DETAILS SERCP8 8.XP.20. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER The truss structure in Figure P8.82 represents part of a bridge. Assume that the structural components are connected by pin joints and that the entire structure is free to slide horizontally at each end. Assume furthermore that the mass of the structure is negligible compared with the load it must support. In this situation, the force exerted by each of the bars (struts) on the pin joints is either a force of tension or one of compression and must be along the length of the bar. Calculate the force in each strut when the angle # = 24 and the bridge supports a w = 9500 N load at its center.
