The force exerted by a machine is called a mechanical force
What else can I help you with?
Why doesn't the principle of mechanical energy conversation hold in situations when frictional forces are present?
Frictional forces result in the conversion of mechanical energy into heat energy. This transformation leads to a loss of mechanical energy in the system, causing the principle of mechanical energy conservation to not hold true in these situations.
Why mechanical energy is not always conserved?
Mechanical energy is not always conserved in the presence of non-conservative forces such as friction, air resistance, or external work. These forces can cause a loss of mechanical energy in a system, converting it into other forms like heat or sound. Hence, the total mechanical energy of a system may change over time due to these non-conservative forces.
Is a towel waving a mechanical or electromagnetic?
A towel waving is a mechanical motion, as it involves the physical movement of the towel due to forces applied by the person waving it. Electromagnetic forces are not directly involved in the waving of a towel.
How do you identify the situations in which conservation of mechanical energy is valid?
Conservation of mechanical energy is valid in situations where only conservative forces are acting on the system, such as gravitational or spring forces. Non-conservative forces, like friction or air resistance, can cause mechanical energy to be lost from the system, making conservation of energy invalid. Additionally, the system must be isolated from external influences for conservation of mechanical energy to hold true.
Can particles be moved?
Yes, particles can be moved by various forces such as gravity, electromagnetic forces, and mechanical forces. These forces can cause particles to change position or be displaced from their original location.
What forces are involved in a tank?
mechanical
Is mechanical forces renewable?
Yes
Which is a cause of mechanical weathering?
physical forces
Can forces work in space?
Yes. Forces work in space. Gravitational, mechanical and electrical forces work in space.
Is belts and wheels mechanical parts that transmit forces?
no
Why doesn't the principle of mechanical energy conversation hold in situations when frictional forces are present?
Frictional forces result in the conversion of mechanical energy into heat energy. This transformation leads to a loss of mechanical energy in the system, causing the principle of mechanical energy conservation to not hold true in these situations.
What is mechanoreceeptor?
It something that senses mechanical forces such as pressure or stretch.
What kind of forces does the human body use to move?
Mechanical.
How many types of forces for mechanical engineer?
4 types
Why vector calculus are used in mechanical engineering?
Mechanical engineering usually deals with forces and their effects on materials. Forces are vectors and so, to study their effects you need to use vector calculus.
Why mechanical energy is not always conserved?
Mechanical energy is not always conserved in the presence of non-conservative forces such as friction, air resistance, or external work. These forces can cause a loss of mechanical energy in a system, converting it into other forms like heat or sound. Hence, the total mechanical energy of a system may change over time due to these non-conservative forces.
What is a mechanical adventage?
Mechanical Advantage;The ratio of load and effort is called mechanical advantage of any machine.Mathematical Formula Of Mechanical AdvantageMechanical Advantage = Load / EffortUnit Of Mechanical AdvantageAs mechanical advantage is the ratio of two forces, therefore it has no unit.
