This is for Inverse Laplace Transform.
What will the Region of Convergence (Pole-zero plot) look like if the pole is equal to zero? The zeroes or the numerator has values but the poles or the denominator is just s.

Moment Area theorem problem. please help
I've been trying to solve the following question for 2 days now and i can't seem to be able to. can someone help me please ?
For the beam shown in Figure 3, the support at A is fully fixed. The beam is tapered however you may consider it to be a beam of 3 varying sections.
Take:
Beam A to B as having 3 times the I value of beam D to end, Beam B to D as having 1.5 times the I value of beam D to end and Beam D to end is 310 UB 46.2 with I = 100 x 106 mm4. Tip: this may be easier to solve using superposition.

A solid shaft made from copper is 90mm diameter and 8m long
A solid shaft made from copper is 90mm diameter and 8m long. If this shaft is joined to a 1.5m long solid steel shaft and 120mm diameter, estimate the maximum shear stress in each material and the total angle of twist of the entire shaft, if a torque of 20KN-m is applied to each end of shaft. GC=40GN/m2 G=90GN/m2
