Rod in tension (25 pts) In a suspension bridge, cables are hung vertically to support the bridge deck. You are working on such a bridge and have to instrument one cable with 1 strain gage to measure the vibrations in the bridge. By sign convention, you select that the voltage of your 1/4 Wheatstone bridge is positive if the strain is positive (cable is in tension). Assume you have a standard Wheatstone bridge as seen in class.

(a) On which branch of the Wheatstone bridge will you connect the strain gage?

(b) You wish to increase the sensitivity of your measurement, by using a 1/2 Wheatstone bridge. Where will you connect the second strain gage in the Wheatstone bridge and how would you mount it on your cable?

(c) Could you build a full Wheatstone bridge to monitor the cable? Explain why.

(d) Could you still use 4 strain gages to increase your sensitivity? Draw how you would mount them on the cable and connect them on your Wheatstone bridge.

explanation:

with mrs. linde, nora reveals her insensitivity and lack of shame about the forgery she committed. she implies that mrs. linde has obviously aged since they last met 10 years earlier, which accounts for nora’s inability to recognize her old friend. although nora seems sympathetic to mrs. linde’s plight, she can’t seem to control herself from boasting about her three children, her husband’s recent promotion, and how good she feels to finally have some money to spend. in a way, she seems to be flaunting her good fortune in front of mrs. linde who, deprived of all these benefits, has come to ask nora for . it is also through her interactions with mrs. linde that we realize something deeper lies under nora’s seemingly childish exterior. she reveals the secret of her forgery to mrs. linde and seems to see herself as quite resourceful for having done it.

in the company of dr. rank, nora is freer than she is with her own husband. she openly laughs with joy at knowing that all the other bank employees will be under her husband’s control. she offers dr. rank a macaroon, apparently forgetting that he knows she is forbidden to eat them. she then quickly covers for herself by claiming that mrs. linde brought them. nora seems much more assertive and free with these other characters, as well as unabashedly willing to scheme, lie, and justify her transgressions as altruistic.  

krogstad provides an interesting parallel to nora. like nora, he too is guilty of committing forgery, for which torvald condemns him and decides to fire him. although krogstad is a man and nora a woman, their crimes of forgery unite them. in fact, krogstad might represent what nora would be like if she were a man and were not strictly scrupulous like her husband is. for example, she tells mrs. linde that "a barrister's profession is such an uncertain thing, especially if he won't undertake unsavoury cases; and naturally torvald has never been willing to do that." perhaps nora would have delved into the unsavory, given how opposite she is to her husband. krogstad's is also the only harsh voice of reality that nora is forced to hear, and that is because he blackmails her for her regaining his job at the bank. finally, torvald’s reaction to krogstad’s forgery seems to foreshadow his harsh and cold reaction to nora’s forgery.
