In the second figure attached it can be seen the free body diagram of the problem.
The equation of equilibrium respect x-axis is
So, cable segmet AC supports bigger tension than segment AB. If then
The equation of equilibrium respect y-axis is
I guess this is the answer, thanks for giving out stuff, kind stranger!
Answer:
2.95 approximately 3
Explanation:
For a heat pump,
COP = Q/W
Where Q = power needed for heating process
W = power input into heat pump.
Power for heating Q = 6.85 kW
Proposed power input to heat pump W = 2.32 kW
Minimum COP = 6.85/2.32 = 2.95
Approximately 3
