The drawing below shows two forces acting on a rigid beam. The blue dot is the center of mass of the beam. The forces (red arrows) are equal in magnitude. Consider the net force on the beam and net torque about its center. Which of the following statements are true? Check ALL that apply. The net force is zero. The net force is not zero. The net torque is zero. O The net torque is not zero.

Consider a block sitting on the ground. In 2 dimensions, the height of the block is 1.65 m, and the width is 0.35 m. There is a force F=47 N applied at the top left corner of the block, and the mass of the block is 27.0 kg, distributed equally throughout the block. What is the torque that the force of gravity generates around the bottom right corner (the location indicated with a red x on the image). Give your answer in units of Nm, to three significant figures. You can treat the block as 2 dimensional. The image is not drawn to scale.

Rank the pictured torques on a solid beam from most negative to most positive. The black dot in the beam is a fixed pivot axis which is located at the very end of the beam (notice that c, e, and f have different pivots!). You may assume that forces are either applied at the end or the center of the beam. Angles that appear to be 90 degrees, are 90 degrees. If torques are equal in magnitude, please indicate this. If any of the torques are zero, please indicate this.

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

In the following mechanism, T1 torque and F1 force act on the AB link. Equilibrium conditionSCD according to the superposition principle, the magnitude of torque required to be applied to the CB.obtain by making drawings? (F1 is vertical from mid point of ABIt is applied directly) O=40⁰, CB=3m, AB=2m

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.

In the figure below, the cg of the pole held by the pole vaulter is 2.54 m from the left hand, and the hands are 0.733 m apart. Assume the vaulting pole has a mass of 3.32 kg.) (a)  calculate the force (in N) exerted by his right hand ( enter the magnitude.) (b)  calculate the force (in N) exerted by his left hand. ( enter the magnitude) (c) If each hand supports half the weight of the pole in the figure below  , show that the second condition for equilibrium (net τ = 0) is satisfied for a pivot other than the one located at the center of gravity of the pole. Explicitly show how you follow the steps in the Problem-Solving Strategy for static equilibrium described above. Figure C is the last diagram

Fy Ex The plant in the picture has mass of 30 kg, and is hanging at a distance of 1.8 meters from the wall. The horizontal rod has mass of 7.8 kg. Assume that its weight is evenly distributed, therefore it can be treated as a single force at the center of mass. The rod is 2 meters long, and there is a cable at a 38° angle supporting it at the end. Using the wall as the axis of rotation, find the magnitude of the downward torque, from both the weight of the rod and the weight of the plant.

Write the necessary equation of the object shown in figure below. Fx R, go Take the origin of the torque equation about an axis perpendicular to the page through the point O.

As a swimmer pulls his arm through the water, various muscles exert forces on the upper arm. The figure below shows a force F exerted on the humerus (upper arm bone) by the pectoral muscle. The muscle is connected to the bone d = 7.10 cm from the center point O of the shoulder joint. Find the magnitude of F, if this force's torque on the arm provides half of the total torque balancing the torque produced by the water pushing against the hand. (Let Fhand = 108 and D = 33.0 cm. ) please solve thank you
