Muscles can only generate tension forces because they are made up of contractile proteins, primarily actin and myosin, that can only pull on each other. When muscles contract, the actin and myosin filaments slide past each other, causing the muscle to shorten and generating a pulling force.

What forces only have an affect on objects that they touch?
Contact forces, such as friction, normal force, tension, and applied force, only have an effect on objects they touch. These forces require physical contact between objects to manifest and influence the motion or deformation of the objects involved.
What forces act on cantilever bridges?
In cantilever bridges, the main forces that act on the structure are tension and compression. Tension forces occur in the upper portions of the bridge where the material is being pulled apart, while compression forces occur in the lower portions where the material is being pushed together. These forces work together to support the load of the bridge and transfer it to the foundations.
A rock attached to a string swings in a vertical circle which free body diagram shows the forces on the rock at the highest point?
At the highest point of its swing, the string tension and the force of gravity acting downwards will be the only forces on the rock. The tension force will point downward and the gravitational force will point towards the center of the circle.
Do balanced forces cause motion?
No. An unbalanced force causes motion, but balanced forces keep a body in motion in a straight line at constant velocity, or at rest at constant 0 velocity.
Matched forces can cause a moving car to go faster?
Matched forces acting on a moving car will not cause it to go faster. The speed of a car is primarily determined by the balance between the engine's power and the forces of friction and air resistance. Matching forces will only help maintain the car's current speed or slow it down, depending on the direction and magnitude of the forces.

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.

At the highest point of its swing, the string tension and the force of gravity acting downwards will be the only forces on the rock. The tension force will point downward and the gravitational force will point towards the center of the circle.
Why can only external forces cause objects to move?
Because of Newton's First Law of Motion.
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.
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 balanced forces cause motion?
No. An unbalanced force causes motion, but balanced forces keep a body in motion in a straight line at constant velocity, or at rest at constant 0 velocity.
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
