net force=75-30=45N;

mass=15kg

so acceleration=45/15=3m/ss

How do you find the coefficient of static friction?

Use the formula: FsMAX=μsFN if you want to do it experimentally, get the two different surfaces, and angle one until the object on top starts moving. take the tangent of the angle that starts the objects sliding past one another, and that is your coefficient of static friction.


Why do lorries need a force to keep them moving at a steady speed?

They need the force to overcome the friction between the lorry and the road.


What is the physical significance of damping coefficient?

The damping coefficient applies both to hydraulic circuits and springs. Hydraulics In general, higher the coefficient or viscosity higher is the tendency to ensure steady flow and hence a higher system efficiency. This is governed by the properties of hydraulic oil selected for use. Springs Higher the coefficient, greater is the tendency for a spring to reach a desired equilibrium position. This is governed by the properties of spring material selected for the applciation.


How is it possible for a car to be accelerating if its speed is a steady 65 mph?

The term accelerating means increasing in speed, so if a car holds its speed steady at 65 mph, it is not accelerating. It is still running its engine, to overcome air resistance and other forms of friction, but that is not the same thing as acceleration.


What uses a cushion of air to reduce friction?

A hovercraft use a cushion of air to reduce friction. In extreme engineering applications there are also air bearings, bearings where a steady flow of air acts as a lubricant between two very finely machined surfaces to keep them apart.


What are the Trim conditions in aircraft?

An aircraft is at trim when it is flying under steady-state conditions (nothing is changing and the airplane is just zipping along).More specifically, trim conditions are when Clbeta (partial derivative of the roll moment coefficient with respect to beta [sideslip angle]), Cnbeta (partial derivative of the yaw moment coefficient with respect to beta [sideslip angle]) and Cmbeta (partial derivative of the pitch moment coefficient with respect to alpha [angle of attack]) are all equal to zero.


How is air resistance related to force?

Gravity is the rate of acceleration at which objects fall to the ground. As an object falls, it pushes air out of its way. Air is pushed upwards in the same direction and with the same amount of force known as its air resistance.Air resistance is relevant to friction because it shows the impact of the object falling on the ground. If there was no friction the object would just drop in an instant.


What is another way to reduce friction?

Friction can cause a lot of damage on rough surfaces. Friction also reduces the efficiency of mechanisms and releases heat that can damage parts, so we often want to minimize its effects by reducing the surface areas that are in contact or using a lubricant such as, oil, grease, and graphite.


What is dynamic error coefficients in control system?

static error coefficients are the error calculated when steady state is reached. so, the dynamic error coefficients give the error calculated with time. it just calculated by taking the inverse Laplace transform of E(s) term resulting in the equation: e(t)=k0 r(t) + k1 r('t) + k2 r''(t) + ... where, k0: position error coefficient k1: velocity error coefficient k2: acceleration error coefficient sks..

What types of friction are on a roller coaster?

It provides undesired slowing of the coaster on its path but it is essential for the brakes to stop it at the station.


What is the opposite of steady?
