20.0 60.0 The three displacement vectors in the drawing have magnitudes of A-4.61 m, B-5.22 m, and C-3.62 m. Find the resultant (a) magnitude and (b) directional angle) of the three vectors by means of the component method. Express the directional angle as an angle above the positive or negative x axis which is less than 90. (a) Number Units (b) Number Units

Solve for all the angles. The only known angle is for m.

In the gear train shown gear 3 is carried on arm 5, Gear 3 meshes with gear 2 and gear 4. The number of teeth on gear 2, 3 and 4 are 60, 20, and 100, respectively. If gear 2 is fixed and gear 4 rotates with an angular velocity of 100 rpm in the counterclockwise direction, the angular speed of arm 5 (in rpm) is 4 2 3 5

Imagine two ordinary gears of different diameters meshed together, with the larger being the driver. If the larger gear has 108 teeth around its circumference and rotates at 5.80 rad/s, the smaller gear, which has only 20 teeth, will rotate at what speed?
