# What is a hinged rod?

The rod is fixed at the point A and is freely hinged to another uniform rod of length 2a and mass m at the point B. Both rods are in equilibrium with the first rod horizontal and the second inclined at angle theta, equals, 30, degrees,θ=30∘ to the vertical, with its unhinged end in contact with the rough floor.

## How do you calculate force hinges?

The hinge force is
`F=m(a_(c)-g)`
`=m[a_(r)hatj-(-ghatj)]`
`=m[((3)/(2)g)hatj+(g)hatj]`
`=((5)/(2)mg)hatj`
Therefore hinge force is `(5)/(2)` mg in vertically upward direction.

## How to calculate angular acceleration of rod?

Angular acceleration (α) can be defined as angular velocity (ω) divided by acceleration time (t). Alternatively, pi (π) multiplied by drive speed (n) divided by acceleration time (t) multiplied by 30. This equation yields the standard angular acceleration SI unit of radians per second squared (Rad/sec^2).

## What are the forces acting on a hinge?

The tension force of the wire, the weight force of the beam and the force of the hinge which can be thought of as a sum of two forces, a force acting in the vertical direction on the beam and a force acting to the right on the beam.

## What is hinge reaction force?

A hinge has two unknown reaction forces and two unknown reaction moments along the coordinate axes that are perpendicular to the axis of the hinge. There is also a reaction force along the axis of the hinge (i.e. does not slide along the z-axis).

## What is the basic formula of torque?

(Refer to Figure 1 for a pictoral representation of these definitions.) Torque is defined as Γ=r×F=rFsin(θ). In other words, torque is the cross product between the distance vector (the distance from the pivot point to the point where force is applied) and the force vector, ‘a’ being the angle between r and F.

## How do we calculate torque?

Measure the distance, r , between the pivot point and the point the force is applied. Determine the angle θ between the direction of the applied force and the vector between the point the force is applied to the pivot point. Multiply r by F and sin θ and you will get the torque.

## How is torque calculated on a hinge?

Hinge Torque Calculator. The torque exerted by the display on the hinge at a particular angle is given by: Torque = Weight x Distance from the Axis of Rotation to Center of Gravity x Cos of the Angle.

## What is the moment of inertia for a rod?

Moment Of Inertia Of Rod Moment of inertia of a rod whose axis goes through the centre of the rod, having mass (M) and length (L) is generally expressed as; I = (1/12) ML2. The moment of inertia can also be expressed using another formula when the axis of the rod goes through the end of the rod.

## How do you find final angular velocity?

v = ω × r . We can rewrite this expression to obtain the equation of angular velocity: ω = r × v / |r|² , where all of these variables are vectors, and |r| denotes the absolute value of the radius.

## How do you find rpm from angular velocity?

Angular Velocity to RPM Conversion Angular velocity in degrees per second can be converted to revolutions per minute by multiplying the angular velocity by 1/6, since one revolution is 360 degrees and there are 60 seconds per minute.

## How do you find angular acceleration with torque?

The angular acceleration can be calculated from how much is the torque applied to the object using the formula α= τ/I .

## How many reactions are in hinged support?

R (externally independent) 3-D Hinged Support At 3-D hinged support there can be three reactions (i) Rx (ii) R (ii) R₂ The 3-D hinged support is also called ‘ball and socket joint’.

## What does freely hinged mean?

Freely hinged means that the rods, individually, are free to rotate about the point, and that there are no frictional forces preventing that, i.e. no resistance to such a motion from the hinge.

## What refers to a negligible body when compared to the distance involved regarding its motion?

What refers to a negligible body when compared to the distances involved regarding its motion? the centroid of the area of the loading curve. The resulting force of a distributed load is always acting at: the area under the loading curve.

## What are the 3 units of torque?

Torque Units: SI, Metric and American There are three common torque units: SI (International Standard) based on Newton meters, Metric based on kilogram force centimeters, and American/ English based on inch pounds.

## Is torque a scalar or vector?

Torque is a vector quantity.

## Is torque the same as moment?

What is the main difference between torque and moment? Torque is the measurement of the turning force of a body, while the moment is the measurement of the perpendicular distance from the point of rotation to the force’s line of action.

## How do I calculate tension?

1. Tension formula is articulated as. T=mg+ma.
2. Tension Formula is made use of to find the tension force acting on any object. It is useful for problems.
3. Tension Solved Examples.
4. Problem 1: A 8 Kg mass is dangling at the end of a string.
