Question

A 150 kg uniform beam is attached to a vertical wall at one end and is supported by a cable at the other end. a) Calculate the magnitude of the vertical component of the force that the wall exerts on the left end of the beam if the angle between the cable and horizontal is θ = 47°.

Answer 1

To calculate the magnitude of the vertical component of the force that the wall exerts on the left end of the beam, use trigonometry to calculate the vertical component of the force exerted by the cable.

Step-by-step explanation:

To calculate the magnitude of the vertical component of the force that the wall exerts on the left end of the beam, we can use trigonometry.

The force exerted by the cable can be split into horizontal and vertical components.

The vertical component is given by: Fv = T * sin(θ), where T is the tension in the cable and θ is the angle between the cable and horizontal.
