Answer:

The resultant moment is 477.84 N·m

Explanation:

We note that the resultant moment is given by the moment about a given point

The length of the sides of the formed triangles are;

l = sin(40°) × 4/sin(110°) ≈ 2.736

Taking the moment about the lower left hand corner of the figure, with the convention that clockwise moments are positive, we have;

The resultant moment, ∑m, is given as follow;

∑M = 250 N × 4 m + 400 N × cos(40°) × 4 m - 400 N × cos(40°) × 2 m + 400 N × sin(40°) × 2 m × tan(40°) - 600 N × cos(40°) × 2 m - 600 N× sin(40°) × 2 m × tan(40°) = 477.837084 N·m

Therefore, the resultant moment, ∑m ≈ 477.84 N·m clockwise.

Maslowich

The true statement about the dot plot is 1 has 4 and 0 dots.

Explanation:

  • after creating a Bar chart 4 is the right answer.
  • The highest among st all the other plots is 1 but 4 shows 3.
  • Taking an average from all the data points 3 comes to the right answer.
  • Median the central Mid-point is 3.
  • Mode also comes to 3.
  • It is skewed on the right due to the 1st one.
  • Skewed shows the data point either increasing or in decreasing.
  • There a to Bi- histograms which has two ups and downs.
  • The true statement has to be as Mean=Median=Mode is 3.
