M Review Constants Part A - Determine the equivalent inductance to the right of terminals b and e, including L4 Learning Goal: To reduce series-parallel combinations of inductors or capacitors to an equivalent inductance or capacitance. Inductors in series and parallel combine like resistors in series and parallel. It is possible to use Kirchhoffs current law to find the current through the equivalent inductance. Moreover, capacitors in series combine like resistors in parallel and vice versa. It is possible to...
Answer: d= 21.8 mm, where I = 64.3 x 10^-6 m^4 and Q= 388 x 10^-6 m^3 HW: 6-2-9 Two channels are connected to form the cross section shown below. The pair of bolts are spaced every s= 200mm along the 6.5m length of the beam. Given the properties for each channel below, find the minimum bolt diameter knowing the allowable average shear stress in the bolts is 25MPa.
