What else can I help you with?
What theorem states that if three forces acting at a point they are in equilibrium then each force is proportional to the sine of the angle between the other two?
The result is a direct consequence of the sine rule.
What is deflection angle?
The deflection angle is the angle between the original path of an object and its new path after it has been influenced by an external force or interaction, such as a collision or a gravitational field. In the context of physics and engineering, it often describes how much an object's trajectory changes due to forces acting upon it. This term is commonly used in fields like optics, mechanics, and navigation. The deflection angle can help in analyzing the effects of forces and predicting future positions or behaviors of the object.
In a right triangle with the hypotenuse c equals 10 and the angle A equals 50 degrees the angle B equals?
In a right triangle with the hypotenuse c equals 10 and the angle A equals 50 degrees the angle B equals: 40 degrees.
What is non-parallel forces?
Non-parallel forces are vector forces having an angle other than zero degrees or 180 degrees direction between them.
Why does a single angle of a pentagon equals 216 degrees?
A single angle of a pentagon can have any value between 0 and 360 degrees.
What happen to the magnitude of forces as the angle between them is increased?
As the angle between forces increases, the component of each force that acts in the direction of the other force decreases. This results in a decrease in the net force acting in the overall direction of the two forces.
What angle do two forces acting on an object produce the minimum net force?
Two forces acting on an object produce the minimum net force when they are acting in opposite directions and have the same magnitude. This occurs when the angle between the two forces is 180 degrees.
What is the definition of angle of shear?
The angle of shear is the angle between the shear plane and the direction perpendicular to the normal stress in a material under shear stress. It represents the amount of deformation occurring due to shear forces acting on the material.
How is the resultant of two forces affected by the angle between the forces?
The resultant of two forces is affected by the angle between the forces through vector addition. When the forces are pointing in the same direction (angle is 0 degrees), the resultant will be the sum of the two forces. As the angle between the forces increases, the magnitude of the resultant decreases until at 90 degrees, the forces are perpendicular and the resultant is the square root of the sum of the squares of the two forces.
What is Lami's theorem?
Lami's theorem states that in a system of concurrent forces acting on an object in equilibrium, the ratio of each force to the sine of the angle between the other two forces is equal. This theorem is used to calculate unknown forces or angles in a system of forces.
If two identical forces are acting on a body find the angle when resultant is maximum?
Zero degrees. This essentially adds up the forces.
What is the resultant of two equal forces of 200N acting at an angle of 90 degrees?
A force of 200*sqrt(2) = 282.8427N (to 4 dp) acting at 45 degrees to the two original forces.
What theorem states that if three forces acting at a point -they are in equilibrium-then each force is proportional to the sine of the angle between the other two?
The theorem you are referring to is the Law of Sines for forces. It states that in a system of forces in equilibrium, each force is proportional to the sine of the angle between the other two forces. Mathematically, this can be expressed as F1/sin(A) = F2/sin(B) = F3/sin(C), where F1, F2, and F3 are the magnitudes of the forces, and A, B, and C are the angles between the forces.
What theorem states that if three forces acting at a point they are in equilibrium then each force is proportional to the sine of the angle between the other two?
The result is a direct consequence of the sine rule.
What is Angle of incidence Why is it important in aviation?
The angle of incidence is the angle between the chord line of an airfoil and the incoming air flow. It is important in aviation because it affects the lift and drag forces acting on the aircraft. By adjusting the angle of incidence, pilots can control the aircraft's lift, speed, and overall performance.
What is the magnitude of the resultant force when forces of magnitude are combined?
The magnitude of the resultant force when forces are combined is determined by vector addition. It is calculated using the Pythagorean theorem for two perpendicular forces or the parallelogram method for forces acting in different directions. The resultant force represents the combined effect of all the individual forces.
If the angle between two forces increases the magnitude of their resultant?
Yes, if the angle between two forces increases, the magnitude of their resultant will also increase. This is because the forces start to add up more effectively in the direction of the resultant as the angle decreases.
