試題 :
1.
A truss supports the loading shown. Determine the equivalent force acting on
the truss and the point of intersection of its line of action with a line
through points A and G.
(20%)
(P.138 Fig. P.3.110)
2.
Two parallel 60-N forces are applied to a lever as shown. Determine the
movement of the couple formed by the two forses
(a) by resolving each force into horizontal and vertical components and adding
the movements of the two resulting couples,
(b) by using the perpendicular distance between the two forces,
(c) by summing the moments of the two forces about point A.
(20%)
(P.152 Fig. P3.150)
3.
For the frame and loading shown, determine the reactions at A and C.
(20%)
(P.187 Fig. P4.70)
4.
The 18-ft pole ABC is acted upon by a 210-lb force as shown. The pole is held
by a ball and socket joint at A and ba two cables BD and BE. For a=9 ft,
determine the tension in each cable and the reaction at A.
(20%)
(P.203 Fig. P4.116)
5.
Determine the reactions at the beam supports for the given loading.
(20%)
(P.254 Fig. P5.63)
