Installing a gas strut on a lid transforms the experience—effortlessly gliding it open with just a gentle push, while the strut ensures it stays securely in place. No more heavy lifting or sudden slams; just smooth, controlled movement that enhances safety and convenience. It’s like giving your lid a reliable partner that makes every use effortless and dependable.

Before calculate the force required for a gas strut, you need to know the weight of the cover.

To measure the weight of the cover plate, it is ideal to use a scale. However, if weighing the cover directly is not feasible or convenient, the following steps can still help determine its weight:

Identify the material of the lid (e.g., glass, acrylic, wood, metal).

Measure the dimensions of the lid: length, width, and thickness.

For a rectangular lid:

For other shapes, use the appropriate formula to calculate the volume.

Obtain the density of the material. The density (often in kilograms per cubic meter, kg/m³, or pounds per cubic foot, lb/ft³) can be found in material property tables or online.

Multiply the volume by the density to find the weight

The center of gravity (CG) is the point where the lid’s weight is evenly distributed. For a uniformly shaped lid (like a rectangle), the CG is at the geometric center.

Measure the distance from the hinge (pivot point) to the center of gravity. This is the lever arm length (L).

Let θthetaθ be the angle between the lid and the horizontal plane (closed position).

The torque (τtauτ) needed to hold the lid open depends on the angle and is calculated by:

• W is the weight of the lid (force due to gravity, W=m⋅gW = m cdot gW=m⋅g where mmm is mass and ggg is the acceleration due to gravity, 9.81 m/s²),
• L is the distance from the hinge to the center of gravity,
• sin(θ) is the sine of the opening angle θthetaθ.

The component of the weight acting perpendicular to the lever arm is given by:

This represents the force due to gravity that acts perpendicular to the plane of rotation of the lid.

Please note that for accurate measurements, ensure the weight of the cover plate is measured on a stable platform and that you maintain balance while standing on the scale.
