Question

Three forces act on the anchor bolt connection shown below. The forces are concurrent at point A. Express all answers to three significant figures with the appropriate units.

Problem #1 

Express force F1 in rectangular vector form. Take F1=20 kN and θ1=50°. 

Problem #2 

Express force F2 in rectangular vector form. 

Problem #3 

Express force F3 in rectangular vector form. 

Problem #4 

Determine the resultant force FR in rectangular vector form. Take F1=20 kN and  θ1=50°. 

Problem #5 

Determine the magnitude Fe of the resultant force. Take F1=20 kN and  θ1=50°. 

Problem #6 

Determine the angle of the line of action θR of the resultant force from the nearest horizontal axis. Take  F1=20 kN and  θ1=50. 

Problem #6 

Determine the required magnitude F1 and line of action θ1 for the resultant force acting at point A to be equal to zero.
