A student performs an experiment to determine the density of an unknown metal cylinder, density of cork, and the specific gravity of kerosene. The student weighs the metal cylinder in air and records it to be 0.98 N. When the cylinder is completely submerged in water it weighs 0.823 N and weighs 0.854 N when completely submerged in kerosene. a. What is the density of the unknown metal cylinder in kg/m3? b. Compute the experimental value of the specific gravity of kerosene. c. A piece of cork has a mass of 0.025 kg in air. When it is fastened to a sinker and the sinker alone immersed in water, the combined weight is 1.960 N. When both sinker and cork are immersed in water, they weigh 0.735 N. What is the density of the cork?
Displacement, Velocity and Acceleration
In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.
Linear Displacement
The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.
