normal strain in bar (2) is measured as –3,300 um/m. Use the dimensions L1 = 1,600 mm, L2 = 1,200 mm, a = 240 mm, b = 420 mm, and c = 180 mm. Determine: (a) the normal strain in bar (1). (b) the normal strain in bar (1) if there is a 1
Rigid bar ABCD is supported by two bars as
shown in Figure P2.7. There is no strain in the
vertical bars before load P is applied. After load
P is applied, the normal strain in bar (2) is
measured as –3,300 um/m. Use the dimensions
L1 = 1,600 mm, L2 = 1,200 mm, a = 240 mm, b
= 420 mm, and c = 180 mm. Determine:
(a) the normal strain in bar (1).
(b) the normal strain in bar (1) if there is a 1 mm
gap in the connection at pin C before the
load is applied.
(c) the normal strain in bar (1) if there is a 1 mm
gap in the connection at pin B before the
load is applied.
