Question
The motor lifts the 60-kg crate with a constant acceleration a = 2 m/s2. Neglect the mass of beam AB.
(a) Determine the tension T in the cable
(b) Determine the reaction force at B
(c) Determine the components of force reaction and the couple moment at the Nixed support A.
Transcribed Image Text:The image depicts a mechanical setup involving a horizontal beam labeled "AB" with a length of 3 meters. The beam is positioned along the y-axis, starting from point A and extending to point B. At point B, a cable is attached, forming an angle of 30 degrees with the horizontal x-axis.
Suspended from the cable is a crate shown to be descending at a speed of 2 meters per second. The cable extends over a pulley system situated atop a brick support column.
Key elements in the diagram:
- **Beam AB:** Horizontal beam with length 3 meters.
- **Point A:** Start of the beam on the y-axis.
- **Point B:** End of the beam where the cable is attached.
- **Cable:** Forms a 30-degree angle with the horizontal x-axis.
- **Crate:** Attached to the cable, descending at 2 meters per second.
- **Brick Support Column:** Houses the pulley system guiding the cable.
This setup might be used to study concepts related to mechanics, such as forces, tension, and angles in equilibrium scenarios.
