In summary, a cylindrical fishing reel with a mass of 0.623 kg and a radius of 1.83 cm has a friction clutch that exerts a restraining torque of 0.614 N · m when a fish pulls on the line. When the reel begins to spin with an angular acceleration of 49.1 rad/s2, the fisherman gets a bite. Using the equations Torque=I(alpha) and I=1/2mr^2, the force that the fish exerts on the line can be calculated by setting the torque equal to rF and solving for F. A free body diagram and a description of attempted solutions or difficulties would be helpful in finding the force in units of N.

Homework Statement



A cylindrical fishing reel has a mass of
0.623 kg and a radius of 1.83 cm. A fric-
tion clutch in the reel exerts a restraining
torque of 0.614 N · m if a fish pulls on the line.
The fisherman gets a bite, and the reel be-
gins to spin with an angular acceleration of
49.1 rad/s2.
What force does the fish exert on the line?
Answer in units of N

Homework Equations


Torque=I(alpha)
I=1/2mr^2
(torque)=rfsin(theta)

You are required to show something here. A free body diagram would be good, plus any thoughts, a description of what you have tried (with working) or an explanation of why you cannot get started.
 

1. How do you calculate the force exerted by a fish on a fishing reel?

To calculate the force exerted by a fish on a fishing reel, you need to know the weight of the fish and the speed at which it is pulling on the line. You can use the formula F = ma, where F is the force, m is the mass of the fish, and a is the acceleration. To find the acceleration, you can use the equation a = v/t, where v is the velocity of the fish and t is the time it takes to reel it in. Once you have calculated the force, you can convert it to the appropriate units (such as pounds or Newtons) for a more accurate measurement.

2. What factors affect the force exerted by a fish on a fishing reel?

There are a few factors that can affect the force exerted by a fish on a fishing reel. These include the weight and size of the fish, the speed at which it is swimming, and the angle at which the line is being pulled. The type and strength of the fishing line and the drag setting on the reel can also have an impact on the force exerted.

3. How does the angle of the fishing line affect the force exerted by a fish on a fishing reel?

The angle of the fishing line can have a significant impact on the force exerted by a fish on a fishing reel. A smaller angle (closer to 0 degrees) means that the fish is pulling more directly against the line, resulting in a higher force. On the other hand, a larger angle (closer to 90 degrees) means that the fish is pulling more horizontally against the line, resulting in a lower force.

4. Can the force exerted by a fish on a fishing reel be greater than the weight of the fish?

Yes, the force exerted by a fish on a fishing reel can be greater than its weight. This is because the force is not just determined by the weight of the fish, but also by its acceleration and the angle at which it is pulling on the line. A larger, faster fish with a more direct pull can exert a greater force on the reel, even if it weighs less than a smaller, slower fish.

5. How can knowing the force exerted by a fish on a fishing reel be useful for anglers?

Knowing the force exerted by a fish on a fishing reel can be useful for anglers in a few ways. It can help them determine the appropriate strength and type of fishing line to use, as well as the appropriate drag setting on their reel. This information can also be used to estimate the size and weight of the fish, which can be helpful in competitions or for bragging rights. Additionally, understanding the force exerted by a fish can help anglers improve their fishing techniques and strategies.
