Unformatted text preview: 2.4-18 A rigid bar AB is supported by two cables CE and
BD as shown in the figure. The cables are identical except for their lengths—cable 3!.) has length it and cable CE has
len th 1.5 h (which means that the length of the bar is L =
h 5). Determine the tensile forces TED and Tc: in the cables due to the lead P acting at point F. 2.4-14 A steel bar ABC (E = 200 GPa) has cross-sectional
area AI from A to B and cross-sectional area A; from B to C
(see ﬁgure). The bar is supported at end A and is subjected
to a load P equal to 40 kN at end C. A circular steel collar
31) having cross-sectional area A3 supports the bar at .3.
Determine the diaplaeernent 30 at. the lower end of the bar
due to the lead P, assuming that the cellar ﬁts snugly at B
when there is no load. (Assume L1 = 2L3 _=-' 250 mm, L; =
225 mm, A1 = 2A3 = 960 1111112, and A2 = 300 m2.) 2.4-16 A rigid bar A361) is pinned at point B and supported by two springs at A and B (see figure). The
springs at A and D have stiffnesses k1 = 15 kam and k2 = 35 kam, respectively. A load P acts at point C. If the angle
of rotation of the 'bar due to the action of the load P is
limited to 2“, what is the maximum permissible load Pmax? ...
