Answer:

$|M_y| = 170.82 \ N.mm$

Explanation:

From the diagram affixed below completes the question

Now from the diagram; We need to resolve the force at point A into (3) components ; i.e x.y. & z directions which are equivalent to $F_x \ , F_y \ , F_z$

So;

$F_x$ = positive x axis

$F_y =$ Negative y axis

$F_z$ = positive z axis

Then;

$|M_x| = F_y *27-F_z*11 = 77 ----- equation(1) \\ \\ |M_z| = F_y*4 - F_x*11 = 81 ---- equation (2) \\ \\ |M_y| = F_x *27 - F_z *4 = ? ---- equation (3)$

From equation (1); Let's make $F_y$ the subject of the formula ; then :

$F_y = \frac{77+11F_z}{27}$

Substituting the value for $F_y$ into equation (2) ; we have:

$(\frac{77+11F_z}{27})4-F_x*11=81 \\ \\ 11(\frac{7+F_z}{27} ) 4- F_x -11 =81 \\ \\ 28+4 F_z - 27F_x = \frac{81*27}{11} \\ \\ 4F_z - 27F_x = 198.82 -28 \\ \\ 4F_z - 27F_x = 170.82 \\ \\ Since \ |M_y| = 4F_z-27F_x \\ \\ Then: \\ \\ \\ |M_y| = 170.82 \ N.mm$

Which of the following is an example of qualitative data

NemiM [27]

Qualitative data is easy to explain. You either agree or disagree in writing. Wrong. You agree, disagree, or qualify. Meaning agree to somewhat extend, but not entirely. So you can agree that people should walk instead of talk in the progressive manner, but not in the impulsive manner.

Balanced- Forces acting on an object are balanced if the ....

choli [55]

Answer:

there is an equal and opposite force
moving

Explanation:

When balanced forces act on an object at rest, the object will not move. If you push against a wall, the wall pushes back with an equal but opposite force. Neither you nor the wall will move. Forces that cause a change in the motion of an object are unbalanced forces.
