University of Warith Alanbaya Civil Engineering Department Mr. Safa'a Sabry M. Engineering Mechanies Chapter Two - 1 Homework 1 Q.4. Determine the magnitude of the resultant force FeF+F and its direction, measured counterclockwise from the positive x-axis. Q.1. Determine the magnitude of the resultant force acting on the screw eye and its direction measured clockwise from the x-axis. F 250 lb 09 30 2 kN 6 kN Q.2. Two forces act on the hook. Determine X- the magnitude of the resultant force. 45° F2= 375 lb Q.5. If0 = 60° and F=450 N, determine the magnitude of the resultant force and its N 00 direction, measured counterclockwise from the positive x-axis. Q.6. If the magnitude of the resultant force is to be 500 N, directed along the N 00, Q.3. Determine the magnitude of the resultant force and its direction positive magnitude of force F and its direction y-axis, determine the measured counterclockwise from the positive x-axis.

The rectangular piece of wood, 76 mm by 174 mm, is used as a compression block. The grain of the wood makes a 30.3º angle with the horizontal, as shown in the figure. Determine the shearing stress (in MPa) on the plane of the grain if the allowable compression stress on the plane of the grain is 20.2 MPa. Round off the final answer to four decimal places.
