What forces act on cantilever bridges?
Compression, Tension, Torsion, and the other is either bending or shear.
What does a unbalanced force cause that a balanced force doesnt?
There is no such thing as "a balanced force" or "a unbalanced force". Only a group of two or more forces can be balanced or unbalanced. An unbalanced group of forces acting on an object causes accelerated motion of the object. A balanced group of forces doesn't.
How much tension is in a rope that holds up a 20-N bag of apples at rest?
The only way the bag of apples can have zero acceleration is that the sum of forces on it is zero. The 20-N downward gravitational force on it must be exactly canceled by some upward force of 20-N. That's the tension in the rope.
What causes a change in motion a balanced or unbalanced force?
Forces on a moving object are balanced only when the object is moving at a constant velocity. Remember, acceleration is a force and a constant velocity is equivalent to zero acceleration. Think of a ping pong ball that you drop from a few meters above the ground: After a short acceleration the ball reaches "terminal velocity" when the air resistance balances the gravitational acceleration. After this, the forces on the ball are balanced (although it is moving, the velocity - speed & direction - of the ball is not changing)
Do all forces of an object cause work to be done?
If a force is applied, but nothing in the system moves, no work has been done. Work is only done when something moves.
What are the three forces acting on the Earth's surface?
Answerthere are two kinds of forces the non-contact force (sometimes called action at a distance forces) and the contact forcesthere are only three types of contact forces the magnetic force, gravity force, and electricity forcethe one that affects the earth is the gravity forcethere is a contact force that affect the earth the friction force

Why is there lava in the middle of the earth?
The pressure on Earth from its own mass, as well as nuclear forces, cause the mantle to be molten. The core is not made of lava. The lava from volcanoes usually only comes from fault line tension, and is very, very far from the "Middle of the Earth."
Why after eating. I get. Asthma?
Because the muscles that cause food to be pushed down your esophagus are partially connected to your trachea. When the esophageal muscles contract, they also cause the tracheal muscles to contract. Causing bronchospasm. I have asthma and this is a p.i.a. It's why I eat only twice a day.
What is the meaning of tension in marathi?
In Marathi, tension is called tension only.
What are three forces that work to stop moving objects on earth?
Right now I can only think of two: Wind Resistance Friction And perhaps surface tension?
What are contact forces and which forces are contact?
Contact forces are forces that can only have an effect on objects that they touch, such as when you contact a box and apply force to move it. you might apply a contact force to bend, tear, stretch, compress, or twist and abject. Tension force, friction force, and elastic force are examples of contact forces.
Why can only external forces cause objects to move?
Because of Newton's First Law of Motion.
Does neck pain cause fatigue?
Absolutely, your neck has many muscles, if you stabilising muscles are atrophised or dormant your main neck musckes take over, this causes bad posture and tension, dizziness, headaches and fatigue. lean your head forward. If it feels heavy you need significant work. only you can fix the imbalance. It is a delicate area only use safe techniques. seek neck exercise, or neck physiotherapy from a physio or doctor. Jump on to youtube to get a good idea of how to do it and why.
Do muscles attach to other muscles?
Muscles do not attach to other muscles. They only attach to bone.
What is cause when muscles pull on bones?
Muscles work by contracting not extending. Thus the mechanics of a body powered by muscles needs to work with that property. Muscle groups are therefore paired, on to pull a lever one way on one side of the hinge and another to pull the other way on the other side.
What keeps the moon from pulling the water right out of earth's oceans?
The gravitational forces are only strong enough to cause tides.
