A 1 200-N uniform boom at f 5 65° to the horizon- tal is supported by a cable at an angle u 5 25.0° to the horizontal as shown in Figure P8.28. The boom is pivoted at the bottom, and an object of weight w 5 2 000 N hangs from its top. Find

(a) the tension in the support cable and

(b) the components of the reac- tion force exerted by the pivot on the boom.

## What is the tension in the cableThe boom in the crane is free to pivot about point P and is supported by the cable that joins halfway along its 18 m length. the cable passes over a pulley and is anchored at the back of crane. the boom has a mass of 1700 kg, distributed evenly an.. |
