Representation of Force

The relative resistance to permanent deformation

The transmissibility principle states that a force's point of application can be shifted anywhere along its line of action without modifying the external reaction forces acting on a rigid body.

Explain the principle of transmissibility of a force.

Tension is defined in physics as the pulling force transferred axially by a string, cable, chain, or similar object.

_____ force is defined in physics as the pulling force transferred axially by a string, cable, chain, or similar object.

Define tension force.

A block of mass $0.2 \mathrm{kg}$ is suspended from the ceiling by a light string. A second block of mass $0.3 \mathrm{kg}$ is suspended from the first block through another string. The tensions in the two strings : Take $g=10.$$\mathrm{m}/{\mathrm{s}}^2$

A rope of length $8 \mathrm{m}$ and linear density $0.5 \mathrm{kg} {\mathrm{m}}^{-1}$ is lying lengthwise on a horizontal smooth floor. It is pulled by a force of $12 \mathrm{N}.$ The tension at the mid-point would be:-

A block of mass $m$ is suspended by a light thread from an elevator. The elevator is accelerating upward with uniform acceleration $a$. The work done by tension on the block during $t$ seconds is $(u=0):$

The minimum acceleration with which a fireman can slide down a rope whose breaking strength is two third of his weight?

A uniform string of length $10 \mathrm{m}$ & mass $20 \mathrm{kg}$ lies on a smooth frictionless inclined plane. A force of $200 \mathrm{N}$ is applied as shown. The tension at the mid point of string is

A man of mass $m$ stands on a crate of mass $M$. He pulls on a light rope passing over a smooth light pulley. The other end of the rope is attached to the crate. For the system to be is equilibrium, the force exerted by the man on the rope will be

Two blocks of masses $m_1=4$ kg and $m_2=2$ kg are connected to the ends of a string which passes over a massless, frictionless pulley. The total downwards thrust on the pulley is nearly

In the figure shown, $m_1=10 \mathrm{k}\mathrm{g},\mathrm{ }{ m}_2=6 \mathrm{k}\mathrm{g},\mathrm{ }\mathrm{ }{m}_3=4 \mathrm{k}\mathrm{g}.$ If $T_3=40 \mathrm{N},\mathrm{ }\mathrm{ }{T}_2=?$

A mass of $10 \mathrm{kg}$ is suspended from a string balance. It is pulled aside by a horizontal string so that it makes an angle of $60°$ with the vertical. The new reading of the balance is

Assertion: string can never remain horizontal, when loaded at the middle, howsoever large the tension may be.

Reason: For horizontal string, angle with vertical, $\theta =90°, T = \frac{W}{2cos\theta } = \frac{W}{2cos90°} =\infty$ .

A pendulum having a bob of mass $m$ is hanging in a ship sailing along the equator form east to west. When the ship is stationary with respect to water, the tension in the string is $T_0$ . The difference between $T_0$ and earth attraction on the bob, is

How can we find the direction of the tension force?
 

What happens if there is no tension on object like a rope or a string?

In free body diagrams, the principle of transmissibility states that the force acting on a body is a _____ vector.
