3. Replace the force system acting on the beam by an equivalent force and couple moment at point A (10 points). 3.00 KN 2.50 KN 1.50 kN, 30 V А B 2 m 4 m 2 m + 4. For your solution for problem 3, determine the distance from the line of action of the resultant to point A. This is how far you would have to displace your resultant from A for the resultant force to cause an equivalent moment (5 points). 5. For your solution for problem 3, determine the x-intercept of the resultant force. That is, determine the location along the span of the beam measured from A through which the resultant force would pass to cause an equivalent moment. Verify your answer by using trigonometric functions and your answer for problem 4. Hint - draw the line of action of your resultant through A and then translate that resultant the distance you calculated for problem 4. Form a right triangle where your distance for problem 4 is one leg of the triangle, and the angle the translated resultant makes with the horizontal is one angle of the triangle (10 points). 6. Repeat problem 5, but this time determine the x-intercept of the resultant measured from B (5 points). nape 2 of 3
