What else can I help you with?
Is pressure internal or external?
Pressure can be both internal and external. Internal pressure refers to the force exerted by a fluid within a closed system, while external pressure can be the force exerted by a substance or object outside of the system onto the system.
Is a bending force an external force or an internal force?
A bending force is an external force acting on an object that causes it to bend or deform. It is typically applied to an object from the outside to induce bending or flexing.
Is body weight an internal or external force?
Body weight is an internal force because it is the force exerted by the mass of an object (in this case, the body) due to gravity acting on it. It is a result of the interaction between the body and the Earth's gravitational field.
What is the difference between pressure and stress?
Pressure is the external force acting over a unit surface area of a material. Stress is an internal force acting over a cross sectional area within the material. It may also be thought of as the internal resistive response of a material to the applied external pressure. They both have the units of force / area. think it as- suppose we have a cubical solid mass. we apply external force of few magnitude on it and this force will try to deform the cube. at the same instant an internal force will generate within the cube that will try to maintain the shape and size of the cube i.e. this internal force will work against the applied external force. this induced force within the cube is stress.
Is weight a external force or an internal force?
Weight is considered an external force because it is the force exerted by gravity on an object due to its mass. It is not generated by the object itself, but rather acts on the object from the outside.
What muscles aid in breathing?
external/ internal intercostals
What is the difference from respiration and breathing?
Internal Respiration: Is changing food (glucose) into energy. External Respiration: Is breathing in and out.
What types of forces act on structures?
external force and internal force
Is pressure internal or external?
Pressure can be both internal and external. Internal pressure refers to the force exerted by a fluid within a closed system, while external pressure can be the force exerted by a substance or object outside of the system onto the system.
What is internal and external forces?
An internal force is a force acted upon by an object to force another object's movement internally. An external force is a force exerted on an object based on the objects position and force applied on the object which causes the opposite forces change in motion.
What element of a security force include the mission of protecting against internal and external threats?
Border guards are the element of a security force include the mission of protecting against internal and external threats.
Is a bending force an external force or an internal force?
A bending force is an external force acting on an object that causes it to bend or deform. It is typically applied to an object from the outside to induce bending or flexing.
What feature sculpted on earth's surface by internal or external force?
buthole
What does internal and external respiration mean?
External respiration refers to the act of mechanically pulling air into the lungs via breathing. Internal respiration is the exchange of gasses from blood to tissue and vice versa.
Internal forces?
A force internal to the system under consideration. Whether a force is regarded as internal or external depends on how the system is defined and classified, and is largely a matter of convenience. In biomechanics, the human body is generally regarded as the system and any force exerted by one part of the body on another is an internal force. Muscle contractions produce internal forces, which move a joint. Compare http://www.answers.com/topic/external-force.
Is body weight an internal or external force?
Body weight is an internal force because it is the force exerted by the mass of an object (in this case, the body) due to gravity acting on it. It is a result of the interaction between the body and the Earth's gravitational field.
What is the difference between the internal and external obliques?
The internal obliques are muscles located underneath the external obliques. The external obliques are more superficial and run diagonally on the sides of the abdomen, while the internal obliques are deeper and run perpendicular to the external obliques. Both muscles help with twisting and bending movements, but the internal obliques also aid in breathing and trunk stability.
