Which of the following most nearly gives the y- component of P with respect to x and y axis?  a. 50 N b. 70 N c. 80 N d. 60 N 2. Which of the following most nearly gives the y- component of P with respect to x’ and y axis?  a. 80 N b. 100 N c. 70 N d. 50 N 3. Which of the following most nearly gives the y- component of P with respect to x’ and y’ axis? a. 95.4 N b. 86.6 N c. 75.7 N d 82.5 N

Two forces F1 and F2 act on the screw eye. If theirlines of action are at an angle θ apart and the magnitude ofeach force is F1 = F2 = F, determine the magnitude of theresultant force FR and the angle between FR and F1.

A beam is subjected to force as shown in the figure below. Try to analyze the reaction force of the beam at point A and point C. Assuming that the EI of the entire beam section is constant, try to draw the shear curve and bending moment diagram of the beam. (Moment Curve).
