The beam below is supported at A and B. F1 and F2 in kN are given in P21 and P22 respectively. F3 in kN is given in P23 and the couple in kN.m is given in P24. Assume that F1, F2, F3 act on the top surface of the beam as shown. In relation to point A, determine the magnitude and direction of a single force that has the same effect on the beam as F1, F2, F3 and the couple.
Determine the distance along the top of the beam from A that the line of action of the single resultant force acts on the beam.
The magnitude of the single resultant force in kN rounded to 1 DP is
ANS
The smaller angle rounded to the nearest degree that the line of action of the single resultant force makes with the top of the beam is
The distance in metres from A to where the line of action of the single resultant force crosses the top of the beam in metres rounded down to 2 DP is

Q. Illustrate what are the weights in pounds of liquid gallons? Answer:- First you should know the specific gravity of the liquid then you can compute the weight by multip
Unbalanced forces cause accelerations. In this case, the unbalanced force is directed opposite the book's motion and will cause it to slow down. To verify if the forces acting
