The problem you've uploaded is related to torque (momen torsi) and muscle force (gaya otot). Let's break it down step by step based on the image and the questions:

### a. Determine the muscle force and torque in the image (a), given that:
- The force \( F_t = 475 \, \text{N} \) 
- The distance from the muscle insertion to the axis (the moment arm) \( r = 20 \, \text{cm} = 0.20 \, \text{m} \).

The torque \( \tau \) is given by the formula:
\[
\tau = F \times r
\]
where:
- \( F \) is the applied force (muscle force).
- \( r \) is the distance (moment arm).

Substituting the values:
\[
\tau = 475 \, \text{N} \times 0.20 \, \text{m} = 95 \, \text{N} \cdot \text{m}
\]

Thus, the torque is \( 95 \, \text{N} \cdot \text{m} \).

For the muscle force, if the question is asking to find it based on the given torque and the length of the moment arm, you already have \( F_t = 475 \, \text{N} \).

### b. Explain the condition in the image (b), including the force and torque:
- In the second image, the angle of the arm may be different from the first, which would affect the torque calculation.
- If the muscle force is acting at an angle, the torque calculation would also need to consider the perpendicular distance from the axis of rotation to the line of action of the force. The force is likely applied at an angle, so the torque may involve a trigonometric adjustment, typically using the sine or cosine of the angle between the muscle force direction and the arm.

If the angle or additional details are provided, we could refine the torque calculation.

Would you like to explore this further or need additional explanations on any specific part? 

Here are some related questions:
1. How does the angle of the applied force affect the torque calculation?
2. What happens if the moment arm changes in length?
3. Can you explain how to calculate torque when the force is applied at an angle?
4. How does the muscle force relate to the torque generated in this system?
5. What are other real-life applications where torque plays a role?

Tip: Always consider the angle between the force and the moment arm when calculating torque for accuracy!
