Because in theory we study regarding a perfect material but in reality the material will have many imperfections which decreases the stress required to deformed a material.
Median signal strength is a number such that the actual signal is higher than that number 50% of the timeand lower than that number 50% of the time.
HDPE has higher density therefore it has greater tensile strength
A characteristic strength is the strength of the material used for design purpose, and is statistically defined by the lower 5% fractile of a bell curve. Compressive strength is a generic term that could refer to anything
Shear strength of fine sand is determined by the angularity of the sand particles, the grading of the sand. These two features governs the critical state shear strength parameters of the sand. Density, however, dictates the peak shear strength of the sand. i.e. the denser the sand, the higher the peak shear strength. But the critical shear strength remain the same. The denser the sand, the lower the void ratio. Shear strength of fine sand is determined by the angularity of the sand particles, the grading of the sand.

it Gives Better estimation and assumption on how much it could carry. By logic, higher strength concrete is used on larger loads therefore, it is still not sure if the loads will be larger than the specified concrete strength. Therefore, having lower permissible strenth helps designers to have allowances for loadings to ensure safety
Possible reasons for actual yield being lower than predicted include: incomplete reactions due to impurities or side reactions, loss of product during isolation or purification processes, and human error in measurements or calculations.

The actual mechanical advantage (AMA) of a machine is always less than the ideal mechanical advantage (IMA) due to factors such as friction, inefficiencies in the machine's design, and other losses of energy. As a result, the actual output force of a machine is typically less than the input force required to operate it, leading to a lower actual mechanical advantage compared to the ideal mechanical advantage.
The strength of the chew. Lower the number higher the strength
The pressure of acetic acid in the gas phase is lower than predicted by the ideal gas law due to intermolecular interactions such as hydrogen bonding between acetic acid molecules. These interactions cause the gas molecules to be more attracted to each other, resulting in decreased pressure compared to what would be expected for an ideal gas.
You need lower body strength in football so you can withstand even the hardest push or throw. Football is all about strength but also about endurance.
The actual Coefficient of Performance (COP) may be lower than the theoretical COP due to factors such as energy losses in the system, inefficiencies in the equipment, variations in operating conditions, and discrepancies between real-world performance and idealized models. These factors can result in the actual system consuming more energy to produce the desired output compared to what would be predicted by the theoretical COP.
It will be LOWER than predicted.
The ideal body type for bobsledding typically features a combination of strength, power, and mass. Athletes often have a muscular build with a strong upper body and core, which aids in the explosive push during the start. A lower center of gravity helps with stability and control in the sled, making shorter, stockier athletes advantageous. Overall, a balance of speed, strength, and agility is crucial for optimal performance in the sport.

The glute hamstring machine is beneficial for lower body strength training because it targets and strengthens the glutes, hamstrings, and lower back muscles. This can improve athletic performance, reduce the risk of injury, and enhance overall lower body strength and stability.
The recommended exercise for building lower body strength with an emphasis on the deadlift over the squat is the deadlift itself. The deadlift primarily targets the muscles in the lower back, glutes, hamstrings, and core, making it an effective exercise for overall lower body strength.
