Question

On the complex plane, draw the position of the complex number z(t) as a function of time

t z(t) = 2e^( it+i0 ), = 2 , 0 = /4

for t=0, 0.1, 0.5, 0.8, 1.0s

2 b' Figure 2 Given an unreformed block (figure 2) and we label 3 corners a, b and c. ab and ac are perpendicular to each other. The side length ab=1m and a 2m. Due to some deformation, b is displaced to b', c to c', and a is unchanged. The length bb'-1mm and cc'-2mm. What is the shear strain? (hint: use the definition of shear strain; see class notes.) Show intermediate steps to get full credit.

Explanation / Answer

use the formula,

shear strain=deformation/original length

=cc'/ac

=2*10^-3/(2)

=1*10^-3 or 0.001 is answer
