**Problem Statement:**

The robot arm is elevating and extending simultaneously. At a given instant, the following data are provided:
- Angle \( \theta \) = 29°
- Angular velocity \( \dot{\theta} \) = 36 deg/s
- Angular acceleration \( \ddot{\theta} \) = 112 deg/s²
- Length \( l \) = 0.62 m
- Linear velocity \( \dot{l} \) = 0.32 m/s
- Linear acceleration \( \ddot{l} \) = -0.38 m/s²

Compute the radial ( \( F_r \) ) and transverse ( \( F_\theta \) ) forces that the arm must exert on the gripped part \( P \), which has a mass of \( m \) = 12.8 kg. Compare with the case of static equilibrium in the same position.

Assume \( d = 0.82 \) m.

**Diagram Explanation:**

The provided diagram illustrates a robot arm operating in a plane. It includes the following key elements:
- A fixed base from which the arm elevates.
- The arm itself extending outward.
- The elevation and extension are measurable by the angle \( \theta \) and length \( l \) respectively.

The forces are acting on point \( P \), located at the end of the arm, which has mass \( m \). The diagram shows:
- \( y \)-axis, \( x \)-axis, representing the coordinate system.
- \( d \), representing the distance from the base to a pivot joint on the arm.
- \( \theta \), representing the arm's elevation angle relative to the horizontal.
  
**Answers:**

The answers are organized in two categories: Dynamic and Static.

**Dynamic Forces:**
- Radial Force: \( F_r \) = ____ N
- Transverse Force: \( F_\theta \) = ____ N

**Static Forces:**
- Radial Force: \( F_r \) = ____ N
- Transverse Force: \( F_\theta \) = ____ N
