A 1,175 N dowel is held in place by a light wire at an angle = 35.0° to the horizontal as shown in the figure. The dowel is attached to a pivot at the bottom, and a mass of weight w = 1,875 N hangs from its top. The dowel makes an angle of ϕ = 55.0° with the horizontal. Assume the dowel is uniform. a- find the tension in the supporting wire in KN

b-Find the components of the reaction force (in kN) exerted by the floor on the dowel.
horizontal component:
magnitude kN
direction left or right
vertical component:
magnitude kN
direction upward or downward

The midpoints? a, b, and c are marked on the histogram. match them to the indicated scores. which? scores, if? any, would be considered? unusual?

Suppose you plot the distance traveled by an object at various times and you discover that the graph is not a straight line. what does this indicate about the object's acceleration?

7. see worksheet 1 for values of variables x1, x2 and x3 and answer the following questions: a. for each variable find the mean, median, coefficient of skewness, range and population standard deviation. b. compared to variable x1, how are the mean and median affected by extreme values (outliers) seen in x2 and x3. c. is the median or mean the better measure of location for x2 and x3? explain. d. explain the differences in the magnitudes of the skewness coefficients for the three variables. e. what is the relationship between the range and standard deviation looking across the three variables?
