Problem 2: Please answer sub-parts A & B. Thanks again!
(A) The strength of structural steel can be controlled by adjusting the grain size. For high strength, should
the grain size be large or small? Why?
(B) If you are capable to control the grain size of solder
interconnects in electronic devices, for high
strength should the grain size be large or small? Why?

I need help with question 1 and 2, can anyone help me please. 1. steel wire is used to attach a balloon on a solar panel boom so that the actuators can be tested. Actuators are the devices that re used to extend the panels from their slowed position during launch to their final extended on- orbit configuration. The balloon must be filled with Helium gas such that the weight of the panels is balanced. Solar panels and their booms...
