Chapter 4, Problem 130P

Determine the moment of the force F about point A in terms of F and d. Use (a) the scalar method; and (b) the vector method.

Replace the loading system by an equivalent resultant force and specify whre the resultant’s line of action intersects the member AB measured from A.

Replace the three forces acting on the bent pipe by a single equivalent force R. Specify the distance d from point O to the point on the x-axis through which the line of action of R passes: 50 lb 40 lb 10 10" 10" 60 lb

Determine the magnitude of the resultant force F(R). Determine the angle between the resultant force and the x axis. And finally specify where the resultant’s line of action intersects member AB, measured from point A. (y = ….. ft above A)

The horizontal top of a concrete column is subjected to the system of forces shown. Represent the resultant of all forces as a force R at point O

Replace the concurrent cable forces acting on the plate shown by a single resultant force R. Also, findthe coordinates of the point where R intersects the plate. Express R in rectangular form.

Compute the values of force T and its direction  θ of the force system shown if the force system has a resultant of 500 N pointing leftward along the x-axis.

Calculate the Cartesian force vectors for F: and F2. Then determine the resultant force vector that is the sum of the force vectors F: and F2. Note that a = 15° and 8 = 40°. Express your resultant as a Cartesian vector, and state the magnitude of the resultant. F, = 35 Ibs 2 ft -1 ft 3 ft F, = 40 Ibs y N 4

Handle forces F1 and F2 are applied to the electric drill. Replace this force system by an equivalent resultant force and couple moment acting at point O. Express the results in Cartesian vector from. Determine the resultant force and the moment of the resultant forse about the point O. Express your answer in terms of the unit vectors i, j and k.
