A uniform beam of weight 100N is pivoted at P as shown. Weights of 10 N and 20 N are attached to its ends. The length of the beam is marked off at 0.1 m intervals. At which point should a further weight of 20N be attached to achieve equilibrium? 0.6m 0.4m 0.1m A C 20N 10N

A beam resting on two pivots has a length of L = 6.00 m and mass M = 77.0 kg. The pivot under the left end exerts a normal force n1 on the beam, and the second pivot placed a distance ℓ = 4.00 m from the left end exerts a normal force n2. A woman of mass m = 61.5 kg steps onto the left end of the beam and begins walking to the right as in the figure below. The goal is to find the woman's position when the beam begins to tip. (a) Use the force equation of equilibrium to find the value of n2 when the beam is about to tip. (b) Using the result of part (c) and the torque equilibrium equation, with torques computed around the second pivot point, find the woman's position when the beam is about to tip.x = (c) Check the answer to part (e) by computing torques around the first pivot point.x = (d)Except for possible slight differences due to rounding, is the answer the same for F and E?

A uniform 8.00 m, 1500 kg beat is hinged to a wall and supported by a thin cable attached 2.00 m from the free end of the beam. The beam is fixed to the wall by a hinge at an angle of 30.0 degrees above the horizontal. The angle between the cable and the beam is 40 degrees. What is the direction of the torque exerted by the beam around the point where the cable is attached? -clockwise -counterclockwise

A 2.0 m long, 200 N uniform ladder, rests with one end against a smooth wall making an angle of 30° with the wall. The coefficient of static friction between the ground and the lower end of the ladder is 0.5. A force F pushes the upper end of the ladder parallel to the wall so that the ladder is on the verge of starting to slip down (static friction has reached its maximum value). The torque of the weight of the ladder relative to the lower end in the ground is: a. 200 Nm b. 620 Nm C. 546 Nm d. 400 Nm e. None of the above I
