QueSTION 2 A 72.0 kg construction worker is eating his lunch at one end of a 21.8 m long, 460. kg steel beam. The other end is bolted into the framework of a new building being constructed. What is the magnitude of the torque about the point where the beam is bolted into place? 3 3 O 5.21x103 Nm O 1.14x105Nm O 1.54x104 Nm 0 6.45x104 Nm 3 3 nuoction 3
A 4.0-m-long 500 kg steel beam extends horizontally from the point where it has been attached to a building that is under construction. A 65 kg construction worker is standing at the far end of the beam. A. Sketch the situation, label variables and centers of gravity. Collect known quantities. B. Where is the center of gravity of the beam? C. What is the gravitational torque on the connection point if no one is standing on the beam? D. What...
A uniform board of length 2.40 m and mass 4.00 kg is pivoted at one end and has a rope attached at the other end, as shown in the figure below. A bucket of mass 2.00 kg is suspended 40.0 cm from the rope. Find: (a) the tension in the rope; (b) the horizontal and vertical forces exerted by the pivot.
Problem 6: A uniform beam of length L = 3.2 m and mass M = 32 kg has its lower end fixed to pivot at a point P on the floor, making an angle θ = 29° as shown in the digram. A horizontal cable is attached at its upper end B to a point A on a wall. A box of the same mass Mas the beam is suspended from a rope that is attached to the beam one-fourth...
A 100 kg construction worker sits down at the end of 4.0 m long, 1000 kg steel beam which is supported by a wall and a cable attached at 1m and 45° to the wall, as shown below. What is the minimum strength in Newtons) that the cable must be rated at to support the load? 45° 1 m 3 m
A 4.80-m-long, 550 kg steel beam extends horizontally from the point where it has been bolted to the framework of a new building under construction. A 75.0 kg construction worker stands at the far end of the beam. What is the magnitude of the torque about the point where the beam is bolted into place?

2) See Figure 2. A 35 kg sign is suspended from the end of a uniform horizontal beam that has a mass of 25 kg and a length of 3.0 m. The beam is attached to a wall by a hinge. A cable with negligible mass is attached to the end of the beam just above the sign and extends to the wall, forming an angle of 30° with the beam. cable beam Physics is Phun Figure 2 a) Sketch...

Name: Date: Balance Lab (Part 1) Explore the "Balance Lab” section of the Balancing Act simulation. 4. Create a situation in which the beam is balanced (without the supports) while there is a single collection of bricks on one side of the pivot and two different collections of bricks on the other side (3 collections of bricks in total in the experiment). Draw the situation on the figure below while making sure to label the masses and the distance to...
