Can anyone please help me with these problems?? I will definitely rate your effort!!! Please help me.

Please do not just copy and paste answers from another website. They are not even the right questions!!!!

1. For the isoparametric bilinear q ' ateral element 4-noded, square element in isoparametric space], write the equations for the shape functions and the derivatives of the shape functions, i.e., M(s, t], BNif'as, and 6NKBL fora' = 1 to 4. (I) For each element shown in Fig. 1, nd Jaoobian [J{s,t]]. (II) Compute |J| at the following locations for each of the elements shown in Fig. 1: (i) s = 0, t = 0 (ii) 3 = 5K7, t: 5;"? (iii) 3 = 6.17, t: 6;"? Given the physical interpretation of |J|, is the element shown in Fig. 1(b] acceptable? (III) The displacement at each node in the element shown in Fig. 1(a) have been determined as listed below. Compute strain at s = 0, t = 0. 111-111u2v2u3o3u4v4-1X10'4in Also nd the corresponding location (1:,y] in physical space where you computed the strain. 3 {0.0) 2'" 4 1 '10 1.1 1'6 . 3.0 1.0 : 1.0 11h J- 0.3 1.0 (0.0) ' 2 (a) (b) Figure 1: 4-noded, bilinear quadrilateral elements in physical space (dimensions are in inches)
