The determinant of the Jacobian of an element for a specific point is found to be equal to det(J)=-0.145. This implies that

X X1 У1 N F B

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.

Please answer all questions.

*2–28. Resolve F, and F, into their x and y components. 60° 30° F = 400 N 456 F = 250 N

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)
