Answer:
The three types of lubrication occurred in the bearing are:
When the lubrication occur in the bearing it play an important role in the rolling life of bearing element. Basically, lubricant task is to reduced the friction.
1) Grease lubricant: Grease contain various type of additives which help in enhance the performance. It consist of oil where thickness are added as, this thickness improved the characteristics of grease.
2) Oil lubricant: This is used to reduced or minimized the friction and the lubricant oil is used to in those vehicles when they are motorized. Bearing lubricant oil is used to higher the speed capability.
3) Solid films: These are non fluid coating surface that are applied in the friction surface for prevention. It is used in very extreme situation where oil and grease types of lubricant does not work.
TexasSure is designed to reduce the number of uninsured drivers and cut costs for responsible Texans, who now pay almost $900 million a year to protect themselves against those with no coverage. Currently, an estimated 20 percent of Texas drivers are uninsured.
TexasSure is the financial responsibility verification program created by the 79th Texas Legislature, Regular Session, in Senate Bill 1670.

Answer:
A,B.C are correct.
Explanation:
The given question can be explained as following-:
The wings have a curvature on them called 'camber', which in essence is half of a venturi create a high pressure area on the bottom of the wing, and a low pressure area on top of the wing. To generate additional lift, the wing's camber (curvature) is increased by extending (in an arc) the leading edge, which is typically done by forcing the leading edge out on tracks, or hinging them out.
The additional camber gives them the additional lift needed for safe operation and control at slower aircraft speeds as when taking off or landing.
Allow the wing to operate at a higher angle of attack. A higher coefficient of lift is produced as a product of angle of attack and speed, so by deploying slats an aircraft can fly more slowly or take off and land in a shorter distance
Therefore, all A,B,C options are correct.
Answer: d) a & b
Explanation: Composite materials are made up of two or more different types of phases which include dispersed phase and matrix phase as most important phases.
- Matrix phase is a types of continuous phase which is responsible for holding of the dispersed phase.It shows good property of ductility.
- Dispersed phase is also known as the secondary phase which is harder in nature than matrix phase.
