An 78.2 kg construction worker sits down 1.93 m from the end of a 1349.4 kg steel beam to eat his lunch. The cable supporting the beam is rated at 15354 N. Should the worker be worried? (To answer that question calculate the tension in the cble. Use θ=29°, L=6.2 m.)

The answer is that the worker should not be worried.

Explanation:

At equilibrium position, the net torque is equal to zero

∑tnet = 0

((-mg) * (D/2)) + ((-mg) * (D-d)) + (T * sinθ * D) = 0

Clearing the tension in the cable T:

Since this tension (14727.24 N) is less than the nominal tension (15354 N), the worker should not be concerned.

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
