i. ii. The state of plane strain at a point is represented by the following components: iii. Ex = 550(10~6), &y = 340(10-6),Yxy : == Draw Mohr's circle to represent this state of strain. -260(10-6) (8 marks) Use Mohrs circle to obtain the principal strains and principal plane. (4 marks) Draw a sketch to illustrate the principal strains and plane. (4 marks)
