Beefy anchor supports are needed to afix suspension bridges to the earth such as these ones from Arthur Ravenel Jr. Bridge in Charleston, South Carolina. Let us model the illustrated orange anchor as a planar truss that is subjected to the cable tension load . Knowing 80 kN, cm, cm, cm and , determine forces , , and in kN in members.

Acompressor compresses a gas, a pump compresses a liquid. for a given pressure ratio, why does it take more work to compress a gas in a compressor than a liquid in a pump? a)- for a given pressure ratio the average specific volume for a gas is much higher than the average specific volume for a liquid. b)- there is no difference. the only difference is the amount of heat generated (not work) c)- for a given pressure ratio the average volurge for a gas is much higher than the average volume for a liquid. d)-there is no difference
