Muscle attachment . When muscles attach to cones, they usually do so by a series of tendons as shown in Figure 1.29. In the figure five tendons attach to the bone. The uppermost tendon pulls at 20.0° from the axis of the bore and each tendon is directed 10.0° from the one next to II. (a) If each tendon exerts a 2.75 N pull on the bone, use vector components to find the magnitude and direction of the resultant force or this bone due to al five tendons. Let the axis of the bone be the +x axis. (b) Draw a graphical sum to check your results from part(a). Figure 1.29 Problem 51.

The x component of vector A is 5.3 units, and its y component is -2.3 units. What is the angle that vector A makes with the +x-axis, measured counter-clockwise from the positive x-axis?
The x-component of vector
R
is
Rx = −27.2
