Chapter 4, Problem 110P

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 force and couple moment system acting on the beam by an equivalent resultant force, and find where its line of action intersects the beam, measured from point O. Set F1= 7 kN, F2= 20 kN and M= 16 kN.m

Determine the resultant R of the system of distributed loads and locate its line of action with respect to the left support for 5.0 kN/m 2.5 kN/m A 2 m 4 m

Replace the loading by an equivalent resultant force and specify its location on the beam, measured from point B. 800 lb/ft 500 lb/ft A B• -12 ft- -9 ft-

Replace the force system acting on the beam by an equivalent resultant force and couple moment at point B.

0.5 m Example Replace the force system acting on the post by a resultant force, and specify where its line of action intersects the post AB measured from point A. 500 N 1m 0.2 m 250 N 30 1 m 300 N SOLUTION 1m A- Equivalent Resultant Force: Forces F, and F, are resolved into their x and y

Determine the resultant R of the system of distributed loads and locate its line of action with respect to the left support for 600 Ib/ft 300 Ib/ft B 3 ft 3 ft 3 ft

Determine the resultant R of the system of distributed loads and locate its line of action with respect to the left support for y 500 Ib/ft 250 lb/ft A B 4 ft 3.5 ft

30 lb/ft 3 ft 6. The post is embedded into a concrete footing so that it is fixed supported. If the reaction of the concrete on the post can be approximated by the distributed loading shown, determine the intensity of w, and w, so that the resultant force and couple moment on the post due to the loadings are both zero. 3 ft 1.5 ft
