A rigid steel bar is supported by three rods, as shown. There is no strainin the rods before the load Pis applied. After load P is app the normalstrain inrod (2) is 560 uin./in. Assume initial rod lengths of L =394 in. and L2-351in. Determine (a) the normal strain in rods (1). (b) the normal strain in rods (1) if there is a 0.032 in. gap in the connections between the rigid bar and rods (1) at joints A and C be the load is applied. (c) the normal strain inrods (1) if there is a 0.032 in. gap in the connection between the rigid bar and rod (2) at joint B before the le applied.

Transcribed Image Text:A rigid steel bar is supported by three rods, as shown. There is no strain in the rods before the load Pis applied. After load Pis applied,
the normalstrain inrod (2) is 560 pin./in. Assume initial rod lengths of L =394 in. and L2=351in. Determine
(a) the normalstrain in rods (1).
(b) the normalstrain in rods (1) if there is a 0.032 in. gap in the connections between the rigid bar and rods (1) at joints A and C before
the load is applied.
(c) the normal strain inrods (1) if there is a 0.032 in.gap in the connection between the rigid bar and rod (2) at joint B before the load is
applied.
