Determine the forces in members abab and cbcb of the truss, and use the correct signs to state if the members are in tension or compression. Set θθ = 30 ∘∘.

small = small current large mag large current

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27

force tends to be low and long diustance masses are high
