#22 A massless rigid beam is held in place at a pivot point at its leftmost edge. A mass of 17 kg hangs 6 meters from the pivot point. What force must be applied upwards at 3 meters to keep the beam in equilibrium (N)?
Added by Amber A.
Step 1
- Mass \( m = 17 \, \text{kg} \) - Distance of mass from pivot \( d_m = 6 \, \text{m} \) - Distance where force is applied \( d_F = 3 \, \text{m} \) - Gravitational acceleration \( g = 9.8 \, \text{m/s}^2 \) Show more…

A massless bar of length L = 9.13m is held horizontally in equilibrium. The bar goes along the y-axis from the origin to r = 9.13mj. Rope 1 is attached at r1 = 9.13mj which exerts a force of F1 = 33.7Ni + 26.1Nj + 65.5Nk on the bar. A mass m = 21.2kg is attached at rm = 5.99mj and exerts a force Fm = -mgk on the bar. Rope 2 is attached at r2 = 3.94mj and exerts a force F2 on the bar. F2 is in the xz plane. Rope 3 is attached to the bar at the origin. The bar is in stationary equilibrium.

2.7 m Examine the diagram to the left. If the horizontal uniform 3.6 m-long beam has a mass of 82 kg, and the location of the support beam is 1.4 m from the wall, what force is the support beam supplying to keep the system in equilibrium? 40° 160 kg

4. A 6.00 m uniform beam of mass 17.0 kg is hinged to a vertical wall. The beam is kept in a stationary horizontal position by an 8.00 m cable. One end of the cable is attached to the other end of the beam while the other end of the cable connects to the vertical wall 4.00 m above the hinge. When a 10.0 kg crate is placed on the beam 5.00 m from the vertical wall the system is in equilibrium. What is the tension in the cable? Compute the magnitude of the horizontal and vertical components of the reaction force on the beam from the wall?
