A power cycle operating at steady state receives energy by heat transfer at a rate ${\dot{Q}}_{H}\text{}at\text{}{T}_{H}=18000K$ and regects

energy by heat transfer to a cold reservoir at a rate${\dot{Q}}_{C}\text{}at\text{}{T}_{c}=600K$ . For each of the following cases, determine

whether the cycle operates reversibly, operates irreversibly, or is impossible.

a.${\dot{Q}}_{H}=500kW,{\dot{Q}}_{C}=100kW$

b.${\dot{Q}}_{H}=500kW,\dot{W}\text{}cyc\le =250kW,{\dot{Q}}_{C}=200kW$

c.$\dot{W}=350kW,{\dot{Q}}_{C}=150kW$

d.${\dot{Q}}_{H}=500kW,{\dot{Q}}_{C}=200kW$

Water stands at a depth H in a large, open tank whose sidewalls are vertical. A hole is made in one of the walls at a depth h below the water surface.

a) at what distance R from the foot of the wall does the emerging stream strike the floor?

b) How far above the bottom of the tank could a second hole be cut so that the stream emerging from it could have the same range as for the first hole?

When a person stands on tiptoe (a strenuous position), the position of the foot is as shown in Figure (a). The total gravitational force on the body, vector F g, is supported by the force vector n exerted by the floor on the toes of one foot. A mechanical model of the situation is shown in Figure (b), where vector T is the force exerted by the Achilles tendon on the foot and vector R is the force exerted by the tibia on the foot. Find the values of vector T , vector R , and θ when vector F g = 805 N. (Do not assume that vector R is parallel to vector T .)

A tow truck pulls a car that is stuck in the mud, with a force of 2500 N as in Fig P5.27 The tow cable is under tension and therefor pulls downward and to the left on the pin at its upper end. The light pin is held in equilibrium by forces exerted by the two bars A and B. Each bar is a strut that is, each is a bar whose weight is small compared to the forces it exerts, and which exerts forces only through hinge pins at its ends. Each strut exerts a force directed parallel to its length. Determine the force of tension or compression in each strut. Proceed as follows Make a guess as to which way (pushing or pulling ) each force acts on the top pin Draw a free-body diagram of the pin. Use the condition for equilibrium of the pin to translate the free-body diagram into equations. From the equations calculate the forces exerted by struts A and B. If you obtain a positive answer, you correctly guessed the direction of the force. A negative answer means the direction should be reversed, but the absolute value correction should be reversed, but the absolute value correctly gives the magnitude of the force. If a strut pulls of a pin, it is in tension. If it pushes, the strut is in compression. Identify whether each strut is in tension or in compression.

As part of your work out, you lie on your back and push with your feet against a platform attached to two stiff springs arranged side by side so that they are parallel to each other. when u push the platform, you compress the springs. You do 80.0G of work when u compress the springs 0.200m from their uncompressed length.

a) What magnitude of force must u apply to hold the platform in this position?

b) How much additional work must you do to move the platform 0.200m farther, and what maximum force must you apply?
