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.

Read the selection below and answer the question. an open boat by alfred noyes o, what is that whimpering there in the darkness? 

 'let him lie in my arms. he is breathing, i know.
 look. i'll wrap all my hair round his neck' – the sea's rising,
 the boat must be lightened. he's dead. he must go.' 


 see - quick - by that flash, where the bitter foam tosses, 
 the cloud of white faces, in the black open boat, 
 and the wild pleading woman that clasps her dead lover 
 and wraps her loose hair round his breast and his throat.
 'come, lady, he's dead.' - 'no, i feel his heart beating,
 he's living, i know. but he's numbed with the cold. 
 see, i'm wrapping my hair all around him to warm him.' -
- 'no. we can't keep the dead, dear. come, loosen your hold.

 'come. loosen your fingers.' - 'o god, let me keep him! ' -
 o, hide it, black night! let the winds have their way! 
 and there are no voices or ghosts from that darkness, 
 to fret the bare seas at the breaking of day. the shift in the poem’s rhythm in the last stanza signifies a resolution to the conflict that the poem is a sonnet the speaker’s confusion an irregular rhyme scheme
