Answer 1

Answer:

Explanation:

EQUIVALENT FORCE SYSTEMS

1. Replace the force and couple system by an equivalent single force and couple acting at point P.

Ans: (a) –0.086i-1.184 kN , 21.6 kN m (b) –270 N, 6885 kN m

2. Determine the magnitude and direction θ of force F and the couple moment M such that the

loading system is equivalent to a resultant force of 600N, acting vertically downward at O, and a

clockwise moment of 400 N-m. Ans: 450.5 N, 27.4O, 1714 N m

3. The systems of four forces acts on the roof truss determine the resultant force and specify its

location along AB measured from point P.

Ans: 1.83m

4. A machine component is subjected to the forces shown each of which is parallel to one of the

co-ordinate axis. Replace these forces by an equivalent force- couple system at A.

Ans: -300i-240j+25k N, -3i+13.5j+9k N m  

5. Four forces act on a 700mm x 375 mm plate as shown. (a) Find the resultant of these forces.

(b) Locate the two points where the line of action of the resultant intersects the edge of the plate.
