This is because if its a suitcase with wheels, half of your body is pushing\pulling the suit case while the wheels are doing some of the work too. This is why when you have a backpack with wheels, it seems lighter than having it on your back.
The middle part of a pulley is called the wheel or sheave. It is the round component that rotates on an axle and around which the belt or rope travels. The wheel is typically grooved to keep the belt or rope in place and provide a better grip for transmitting force.
The component of the applied force that is parallel to the displacement of the object is the only part that performs work on the object. This is because work is defined as force multiplied by the displacement in the direction of the force.
Two simple machines that are part of a bicycle are the wheel and axle and the lever. The wheel and axle allow the bicycle to move forward by rotating, while the lever system is used in the brakes and gears to increase or reduce force applied by the rider.
The force which is responsible to make a drag through a distance of 250 m is the horizontal component of the force 60 N ie 60 cos 40 = 45.96 N Hence the work done = F s = 45.96 x 250 = 11490 joule. The usual formula for work done W = F s cos@ where @ is the angle between the force vector and the displacement vector. Here the weight of the suitcase is perpendicular to the displacement and so the value of cos 90 is zero and hence no work is done due to the weight of the suitcase.
The effort or input force is the part of a lever that applies the force to move an object.

Part time is to only be used on very slippery surfaces.
it is a wedge because is changes the vertical force into a horizontal force to push the wood apart

Yes. They are called "wheels". Rims are only part of a wheel.
roulette wheel is a part of the casino collection in the New York collections and are only found exclusively from the daily chance lottery.
If your suitcase handle is broken, you can try fixing it with duct tape or a luggage repair kit. If that doesn't work, consider contacting the manufacturer for a replacement part or taking it to a luggage repair shop. Alternatively, you may need to purchase a new suitcase.
