i know one is called a ball joint... not sure what the other one is called
yes
that vehicle has a total of 11 grease fittings. two upper ball joints two lower ball joints, two outer and two inner ball joints, two on the idler arm and one on the pitman arm.
There are two general types of joints, movable and immovable. Under the movable category there are four types of joints: Hinge joints: in knees and elbows Pivot joints: in neck Gliding joints: in wrists and ankles Ball-and-socket joints: in shoulders and hips
your arm and hips are one of them
your arm and hips are one of them
your arm and hips are one of them
your arm and hips are one of them
You would not be able to eat (jaw joints) or move (arm, leg, and neck joints).
The degree of freedom (DOF) of a robotic arm can be computed based on the number of the joints and types of the joints. For most robotic arm, the joint is either prismatic or revolute(about one axis), the DOF is simply the total number of the joints.
If the joint between your arm and shoulder was not a ball and socket joint, you could not be able to move your arm. Ball and socket joints allow you to move in most directions. Because of this, you can move your arm up, down, side to side, front and back, and around in a circle. The ball and socket joint is one of the four major kinds of movable joints. (The four major joints are ball and socket joints, gliding joints, hinge joints, and pivotal joints in case you didn't know.)
Joints are located where two bones come together. There are ball and socket joints, there are hinge joints, there are saddle joints there are pivot joints, there are gliding joints and there are condyloid joints. There are 27 bones in the hand alone so there are more than 27 joints in the hand. There are 39 joints in each arm. There are over 300 joints in the human body. There is not enough room to give you an answer for each joint in the human body.
The joints connects the arm to the upper body.
