The weight to material ratio for a parachute depends on various factors such as the size of the parachute, the weight of the payload, and the desired descent rate. In general, a common ratio is 5:1, meaning the parachute should be able to support 5 times the weight of the payload. However, it is best to consult a professional or refer to specific guidelines for more accurate recommendations.

How do you calculate strength to mass ratio?
Strength-to-mass ratio is calculated by dividing the strength of an object or material (such as tensile strength or compressive strength) by its mass or weight. The formula is: Strength-to-mass ratio = Strength / Mass. This ratio helps to assess the efficiency of a structure or material in carrying load relative to its weight.
What is Value to weight ratio?
Value to weight ratio is a metric that compares the value or cost of an item to its weight or mass. It helps in evaluating the efficiency or cost-effectiveness of a product based on its weight. A higher value to weight ratio indicates that the product is more valuable relative to its weight.
What is the difference between apparent specific gravity and absolute specific gravity and bulk specific gravity?
Dry Bulk Specific Gravity does not take into account for anything getting into the permeable or impermeable voids of say a stone by water for instance. Saturated Surface Dry Bulk Specific Gravity takes into account for anything getting into the permeable voids only of say a stone by water. Apparent Specific gravity takes into account for the volume of the impermeable voids and not anything getting into the permeable voids of say a stone by water.
How can I calculate the power to weight ratio of a vehicle?
To calculate the power-to-weight ratio of a vehicle, divide the vehicle's power output (in horsepower or watts) by its weight (in pounds or kilograms). This ratio indicates how much power the vehicle has relative to its weight, which can affect its performance and efficiency.
How can one determine the power to weight ratio of a vehicle?
To determine the power to weight ratio of a vehicle, you need to divide the vehicle's power output (in horsepower or kilowatts) by its weight (in pounds or kilograms). This ratio helps to understand how much power the vehicle has in relation to its weight, which can affect its performance and efficiency.
How do you calculate strength to mass ratio?
Strength-to-mass ratio is calculated by dividing the strength of an object or material (such as tensile strength or compressive strength) by its mass or weight. The formula is: Strength-to-mass ratio = Strength / Mass. This ratio helps to assess the efficiency of a structure or material in carrying load relative to its weight.
Why is nylon used to make parachute's?
Nylon is used to make parachutes due to its high strength-to-weight ratio, which allows for durable yet lightweight construction. Its resistance to abrasion and UV light enhances the parachute's longevity and performance in various weather conditions. Additionally, nylon's elasticity helps absorb shock during deployment, making it a reliable choice for parachute design. Overall, these properties make nylon an ideal material for ensuring safety and effectiveness in parachuting.
What does a 3.0 duratech engine weight?
Hi I'm a nerd. If you calculate the weight times material ratio you will get about 600 pounds heavier than my mom. P.S. Does this mean were freinds?
Does specific gravity has units?
- The specific weight is the weight of a known volume of material at a given temperature and pressure; the unit of measure is kN/m3. - But if you think to relative density: Relative density (specific gravity) is the ratio between the density of the material to be tested and the density of water, at a given temperature and pressure; consequently no unit of measure for this ratio.
What are the key features to consider when choosing a crankset for a single-speed bike?
When choosing a crankset for a single-speed bike, consider the number of teeth on the chainring for desired gear ratio, the material and weight of the crankset for durability and performance, and the compatibility with the bottom bracket for proper installation.
Is there a ratio between a skydiver and a parachute?
For an experienced skydiver, it is 1:1, for a trainee and trainer it is 2:1.
How do you find weight to strength ratio of bridges?
The weight-to-strength ratio of a bridge is determined by dividing its total weight (dead load) by its load-carrying capacity (strength). The dead load includes the weight of the bridge materials and any permanent fixtures, while the load-carrying capacity is typically derived from engineering analyses that account for factors such as material strength and structural design. A lower ratio indicates a more efficient design, as it suggests the bridge can support a greater load relative to its own weight. This ratio is crucial for assessing the overall performance and safety of the bridge.
Why you go for composite material instead of others?
Because, for some uses, composites offer the best characteristics, like best strength-to-weight-ratio.
What is Value to weight ratio?
Value to weight ratio is a metric that compares the value or cost of an item to its weight or mass. It helps in evaluating the efficiency or cost-effectiveness of a product based on its weight. A higher value to weight ratio indicates that the product is more valuable relative to its weight.

What is the ideal motorbike to rider weight ratio?
The ideal motorbike to rider weight ratio is 0.07. The closer the ratio is to zero, the more it feels like one is riding without the motorbike weight, just the rider's.
What is the formula for strength to weight ratio in a dome?
I am looking for the formula to figure strength to weight ratio for a dome that I built for a project
