28. The fishing pole in Figure P10.28 makes an angle of W 20.0° with the horizontal. What is the torque exerted by the fish about an axis perpendicular to the page and passing through the angler's hand if the fish pulls on the fishing line with a force F - 100 N at an angle 37.0° below the horizontal? The force is applied at a point 2.00 m from the angler's hands. 00 m 37.0 20.0° 100 N Figure P10.28

The fishing pole in the figure below makes an angle of 20.0° with the horizontal. What is the magnitude of the torque exerted by the fish about an axis perpendicular to the page and passing through the angler's hand if the fish pulls on the fishing line with a force F = 110 N at an angle 37.0° below the horizontal? The force is applied at a point L = 2.04 m from the angler's hands. N.m Need Help? Watch It Additional Materials 20.0° eBook 120.0⁰ 37.0° F

a meterstick is balanced at the 60.0 cm mark on a fulcrum. A 63.0 gram object is hung from the 10.0 cm mark and a 150 gram object is hung from the 95.0 cm mark. IF the meterstick is in balance and horizontal, what is the mass of the meterstick? What is the total counter-clockwise torque? WHat is the clockwize torque?

A uniform ladder 5.0 m long rests against a frictionless, vertical wall with its lower end 3.0 m from the wall. The ladder weighs 140 N. A man weighing 620 N climbs slowly up the ladder. Start by drawing a free-body diagram of the ladder. What is the actual frictional force when the man has climbed 1.0 m along the ladder? [Hint: Draw a free body diagram to determine what forces are at play. Then use the torque formula (T = Fxrx sine) to find the net torque.]

The fishing pole in the figure below makes an angle of 20.0° with the horizontal. What is the torque exerted by the fish about an axis perpendicular to the page and passing through the angler's hand if the fish pulls on the fishing line with a force F with arrow = 90 N at an angle 37.0° below the horizontal? The force is applied at a point L = 2.20 m from the angler's hands.

A wrench 0.8 meters long lies along the positive y-axis, and grips a bolt at the origin. A force is applied in the direction of (0,-1,-3) at the end of the wrench. Find the magnitude of the force in newtons needed to supply 100 newton-meters of torque to the bolt. Force: newtons

A thin cord is wrapped around a uniform grindstone of radius 0.30 m and mass of 25 kg supported by bearings that produce negligible friction torque. The cord exerts a steady tension force on the grindstone, causing it to accelerate from rest to 60 rad/s in 12 s. (lgrindstone = 5 What is the magnitude of the tension force of the cord? O 5.6 N 11.3 N O 18.7 N O 37.5 N
