As the screw is rotated, it creates a mechanical advantage by converting rotational motion into linear motion, allowing it to fasten materials together by exerting force and creating a clamping effect. Adding load to a ship will displace more water, causing the ship to sink deeper into the ocean.

Why is jack screw provided with a long arm?

moment of force (torque) i.e. the turning effect of a body(here,screw jack)= force applied X perpendicular distance of force from the axis of rotation. so in order to produce maximum turning effect of the screw jack by a force, the force is applied at a point on the body for which the distance from the axis is maximum so that the given force provides maximum torque to turn the screw jack. Thus,the screw jack is provided with a long arm.


What is a screw made up wrapped around a post or a rod?

A screw is composed of a helical ridge wrapped around a cylindrical post or rod. As the screw is rotated, it creates a mechanical advantage by converting rotational motion into linear motion, allowing it to fasten materials together by exerting force and creating a clamping effect.


What will be the effect of displaced water if load is added into ship float in ocean?

Adding load to a ship will displace more water, causing the ship to sink deeper into the ocean. The buoyant force acting on the ship will increase to counteract the added load, keeping the ship afloat at a new equilibrium position.


When a wave passes a ship at sea how does the wave effect the ship?

the waves travel through water, but they do not carry the water with them. The ship moves up and down as the wave passes under it. The ship does not travel with the wave!


What does Triple Screw Steamer mean?

Single (Sgl.) screw: only one propeller what in Spanish is HELICE: on the aft. Double: 2 = dos helices; two propellers (two fans) one on each side (Stern) Triple: probably on the back (Stern)
