HOMEWORK SET 2

DUE : TUESDAY, 26 MAY 2009

1)

Determine the magnitude of the resultant force acting on the bracket and its direction measured counterclockwise from the positive u axis.

2)

The device is used for surgical replacement of the knee joint. If the force acting along the leg is 360 N, determine its components along the x and y' axes.

3) Resolve F1

into components along the u and υ

axes and determine the magnitudes of these components.

4) If the magnitude of the resultant force acting on the eyebolt is

600 N and its direction measured clockwise from the positive x axis is θ

= 30o

, determine the magnitude of F1

and the angle Φ

5) Determine the magnitude of F1

and its direction θ

so that the resultant force is directed vertically upward and has a magnitude of 800 N.
