Horizon control refers to maintaining the aircraft's pitch and roll angles. Poor maintenance can lead to loss of control and accidents.

• Horizon control is the process of maintaining the aircraft's pitch and roll angles using instruments such as the attitude indicator and artificial horizon.

• If the horizon is not maintained well, the aircraft can lose control and enter into dangerous attitudes such as a stall or spin.

• Poor horizon control can also lead to spatial disorientation, ...read more

Creep control is the process of preventing or reducing the deformation of a material under a constant load over time.

• Creep is a phenomenon where a material deforms over time under a constant load or stress.

• Creep can be controlled by reducing the temperature, decreasing the load or stress, or using materials with higher strength.

• For example, in the aerospace industry, creep control is important for preventing deformation of materials in high-temperature environments.

• In the con...read more

Forward snaking and reverse snaking are techniques used in cable laying.

• Forward snaking involves pulling a cable through a conduit from one end to the other.

• Reverse snaking involves pushing a cable through a conduit from one end to the other.

• Both techniques are used to lay cables in tight spaces or areas with limited access.

• Reverse snaking is often used when the cable needs to be protected from damage during installation.

• Forward snaking is often used when the cable is already...read more

Production in longwall is calculated by measuring the amount of coal extracted per unit time.

• Measure the amount of coal extracted per unit time

• Calculate the production rate by dividing the amount of coal extracted by the time taken

• Use sensors and monitoring systems to track the production

• Adjust the longwall cutting speed and depth to optimize production

Staggering in longwalls refers to the practice of leaving pillars of coal between adjacent panels to provide support.

• Staggering is a technique used in longwall mining to prevent the collapse of the roof and walls of the mine.

• It involves leaving pillars of coal between adjacent panels to provide support.

• The size and shape of the pillars depend on the geology of the mine and the equipment used.

• Staggering can help to increase the safety and efficiency of longwall mining operatio...read more

Dynamic pressures act on supports by exerting force and causing movement.

• Dynamic pressures are caused by fluid flow or wind gusts.

• These pressures can cause vibrations and oscillations in the structure.

• Supports must be designed to withstand these forces and prevent failure.

• Examples of supports include beams, columns, and braces in buildings and bridges.

• Proper analysis and testing is necessary to ensure the safety and stability of the structure.
