as a trailer is towed in the forward direction, the firce F = 500N is applied to the ball of the trailer hitch. Determine the moment of this force about point O...static problem​

Answers

Answer 1

Answer:

The right approach is "128.578 N-m".

Explanation:

Given:

Force,

F = 500 N

then,

[tex]F_y=500 \ Cos30[/tex]

[tex]F_x=500 \ Sin 30[/tex]

Now,

The moment of force will be:

⇒  [tex]\Sigma M_0=500 \ Cos30\times (275)+500 \ Sin30\times (38)[/tex]

             [tex]=500\times \frac{\sqrt{3} }{2}\times 275+500\times \frac{1}{2}\times 38[/tex]

             [tex]=128578.493[/tex]

or,

            [tex]=128.578 \ N-m[/tex]

8. In the commercial production of sugar (sucrose), the product crystals are washed and centrifuged to partial dryness. The crystals are then sent through a rotary dryer where they are contacted with a hot stream of air that reduces the moisture content from 1:0 wt% to 0:1 wt%. The ratio of wet sugar to inlet air fed to the dryer is 3.3 kg wet sugar/kg inlet air. The inlet air contains 1.5 mole% water. (a) Draw and label the flowchart and do the degree-of-freedom analysis. (b) Taking a basis of 100 kg of wet sugar fed to the dryer, calculate the mass of water and its mole fraction in the air leaving the dryer.
