**Toggle Clamps: Analyzing Force**

The figure below shows a toggle clamp. If force F is exerted as shown, determine the vertical clamping force at E.

[Include detailed explanation of any graphs or diagrams if presented here.]

**Explanation of Diagram:**

The diagram typically illustrates a mechanical setup of a toggle clamp, which is a fastening device used to hold a workpiece in place. The toggle clamp shown in the figure is subjected to an external force labeled as F. The objective is to calculate the resultant vertical clamping force at point E.

To solve this problem, follow these steps:

1. **Identify Points and Forces:** Clearly mark the locations where forces are applied and their directions.
2. **Analyze Lever Arms:** Determine the length of lever arms involved in the clamping mechanism.
3. **Apply Static Equilibrium Equations:** Use equations of static equilibrium to relate the exerted force F to the clamping force at E.
4. **Calculate Moments:** Consider moments around relevant points to simplify the calculations.

The calculated clamping force at E will help in understanding how effective the toggle clamp is in securing the workpiece under the applied force F.

**Note:** Ensure to refer to the specific diagram provided in your materials for accurate comprehension and analysis.

## Determine the Force in the Link DE of the Metal Cutter

### Description
The image above presents a mechanical drawing of a metal cutter, with specific measurements and force applications detailed. The aim is to determine the force exerted in the link DE.

### Components and Measurements:
- **Handles**: Two handles are extending outward from the cutter. Each handle is 400 mm in length.
- **Forces**: Each handle has a force of 100 N applied at an angle of 15 degrees to the horizontal.
- **Pivot Points**: 
  - Points A and F are pivots located on the handles.
  - Point D, located on the base, is 30 mm from C and 60 mm from the lower edge, while point E is adjacent.
- **Linkage**:
  - Bars connect from points E to A and D to F, each bar being disjoint at point E.
- **Angles**:
  - The angles at various points are specified to be 15 degrees.

### Detailed Measurements:
1. **Length Specifications**:
    - Distance from handle pivots to end: 400 mm.
    - Distance from handle connection to link DE connection point (measured horizontally): 20 mm.
    - Distance between base points (C to D and D to edge): 30 mm vertically and 30 mm horizontally.

2. **Angle Specifications**:
    - Forces are applied at 15 degrees both above and below the horizontal axis to the handles.
    - Additional angles around the pivot points and the connection link are also 15 degrees.

### Analysis Explanation:
To determine the force in the link DE, one would need to employ principles of static equilibrium and potentially use methods such as:
- **Free Body Diagrams (FBD)**: Drawing FBDs for the entire system to isolate forces.
- **Moment Equilibrium**: Summing moments around points to solve for unknown forces.
- **Force Equilibrium**: Summing forces in horizontal and vertical directions to find unknowns.

### Summary:
To find the force in the link DE:
1. Set up the equilibrium equations for the cutter system: ΣF_x = 0, ΣF_y = 0, and ΣM = 0.
2. Solve the simultaneous equations derived from the FBD for unknown forces.

This structured approach will help in solving for the force in the link DE.
