Which of the following is correct (select one) Linear and quadratic interpolation functions always give same results Linear interpolation functions always give accurate displacement values Using quadratic shape functions increases the accuracy of results Nono

Determine the magnitude (N) of the force in member BC if F=318N, a=0.6m, b=1.47m, r=1.32m and d=32.31 degrees. Round off only on the final answer expressed in 3 decimal places. Instead of units, indicate C if force is compressive or T if tensile.

1: Determine the magnitude of F, and length y if F;=1500 N and x =1.75 m. You may assume that the tension in a rope on one side of a pulley is equal to the tension in the rope on the other side of the pulley. In making this assumption, you are neglecting the effects of friction. 2m

5a. If lengths a=1.2m, b=3.7m, c=1.6m, d=4, e=1.4m, and f=4.3m, determine the angle (in degree) between the forces F_A and F_B. Answer must include 1 place after the decimal point. 5b. If lengths a=1.1m, b=4.8m, c=1.1m, d=3.2, e=1.3m, and f=3.2, determine the moment (in N*m) caused by force F_A about axis OD. Answer must include 1 place after the decimal point. Negative sign must be included if the rotational tendenct about the OD axis (from O to D) is clockwise. 5c. Find out all support reaction components at the fixed support O after being given all forces and lengths. ( use the 2nd image  named practice problem 5-2 for this question)
