Answer:
R = 148.346 N
M₀ = - 237.2792 N-m
Explanation:
Point O is selected as a convenient reference point for the force-couple system which is to represent the given system
We can apply
∑Fx = Rx = - 60N*Cos 45° + 40N + 80*Cos 30° = 66.8556 N
∑Fy = Ry = 60N*Sin 45° + 50N + 80*Sin 30° = 132.4264 N
Then
R = √(Rx²+Ry²) ⇒ R = √((66.8556 N)²+(132.4264 N)²)
⇒ R = 148.346 N
Now, we obtain the moment about the origin as follows
M₀ = (0 m*40 N)-(7 m*60 N*Sin 45°)+(4 m*60 N*Cos 45°)-(5 m*50 N)+ 140 N-m + (0 m*80 N*Cos 30°) + (0 m*80 N*Sin 30°) = - 237.2792 N-m (clockwise)
We can see the pic shown in order to understand the question.
Answer:
Entropy:
Entropy is the measure of randomness of system.In other words the entropy is the measurement of tendency of system towards the disorder.
The concept of entropy arise from second law of thermodynamics.It is given as follows
Entropy is a extensive property of system .
Entropy of universe = Entropy of system + Entropy of surrounding.
The entropy of the system can be zero,positive and negative.But entropy of the surrounding can not be negative,but it can be zero or positive.
Actually the concept of entropy is difficult to understand because we can not visualize because it is not like beam and like rods.Only we have to realize that there is entropy.

Explanation:
Confidential data is not supposed to be shared amongst others.
I think it’s is false I’m not that sure
Answer:
1. Yes, they are all necessary.
2. Both written and verbal communication skills are of the utmost importance in business, especially in engineering. Communication skills boost you or your teams' performance because they provide clear information and expectations to help manage and deliver excellent work.
