A compound steel (E = 30,000 ksi) bar is subjected
to the loads shown. Bar (1) has a cross-sectional area
of A1 = 0.30 in.2 and
a length
of L1 = 130 in. Bar
(2) has an area
of A2 = 0.30 in.2 and
a length
of L2 = 130 in. Bar
(3) has an area
of A3 = 0.17 in.2 and
a length
of L3 = 40 in. The
loads and angles
are P = 25 kips, ? = 31°, Q = 14 kips, ? = 55°,
and R = 5 kips. Determine the
vertical deflection of end A. A downwards deflection
is positive, while an upwards deflection is negative.
A compound steel (E 30.000 ksi) bar is subjected to the loads shown. Bar (1) has a cross-sectional area of A? -0.30 in.2 and a length of L? - 130 in. Bar (2) has an area of A? - 0.30 in.2 and a length of L? - 130 in. Bar (3) has an area of A3 - 0.17 in.² and a length of L3 - 10 in. The loads and angles are P-25 kips, a-31%, Q-14 kips, 8-55%, and R 5 kips. Determine the vertical deflection of end A. A downwards deflection is positive, while an upwards deflection is negative.
