- A meter stick has a pivot placed ate 30 cm. The following masses are placed at the following locations. The meter stick is basically an inertial balance and thus doesn’t rotate. Sum the torques in order to determine the mass of the meter stick. 500 g placed at 10 cm, 200 g placed at 40 cm and 150 g placed at 75 cm .A force F = (7i + 3j + 3k) N is applied to a point with position vector r = (6i + 3j + k) m. Find the torque due to this force about the axis passing through the origin. (Express your answer in vector form.) Torque= ______ N*MThe 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 = 108 N at an angle 37.0° below the horizontal? The force is applied at a point L = 1.80 m from the angler's hands. (Enter the magnitude in N · m, accurate to at least the nearest integer.) What If? To reel in the fish, the angler now pulls back on the fishing rod, increasing the angle it makes with the horizontal to 41.0°. If the fish still applies the same force in the same direction, what is the increase in the torque exerted by the fish about an axis perpendicular to the page and passing through the angler's hand? (Enter the magnitude in N · m.)
