The next several problems utilize the same data given in this problem statement. I suggest you glance over the next few problems, so that you have an idea of the items you will need to calculate. You may determine that you calculate the items in an order other than that given on the test (doing this is OK!). BUT, be sure you look at EACH problem and provide the answer to that particular problem. Consider the bracket shown in Fig-3. If: • F1 = 10 lb @ -90° • a = 2 ft • b= 4 ft • C = 1 ft then, what is the magnitude of the vertical reaction at point 'A?
