need help asap :<<

Transcribed Image Text:The rigid bar is supported by an 8-cm-long, 8-mm-diameter aluminum wire A and a 10-cm-long, 2-mm-
diameter steel rod B. There is no strain in either before the load of 4000 N is applied. After the load is
applied, a deformation of 4 mm is measured in the wire. Calculate the force P. Answer in N rounded off
to integer.
