What principle governs the motion of a pendulum?
✔✔The motion of a pendulum is governed by the principles of harmonic motion, where
gravitational force and inertia work together to create a periodic swinging motion.
How does torque affect rotational motion in mechanical systems?
✔✔Torque is a measure of rotational force that determines how effectively an object can be
rotated about an axis, influencing acceleration and angular velocity in mechanical systems.
What is the importance of the center of gravity in mechanical design?
✔✔The center of gravity affects stability; understanding its location helps engineers design safe
and balanced structures or vehicles.
How do hydraulic systems amplify force?
✔✔Hydraulic systems use incompressible fluids to transmit pressure, allowing a small force
applied at one point to be converted into a larger force at another point, based on Pascal's
principle.

, What factors influence the thermal expansion of materials?
✔✔Thermal expansion is influenced by material properties, temperature change, and the
dimensions of the material; engineers must account for this in design to prevent structural issues.
How does strain differ from stress in materials science?
✔✔Strain is the deformation of a material due to applied stress, which is the internal force per
unit area within materials; understanding both is crucial for assessing material behavior under
load.
What role does the Reynolds number play in fluid mechanics?
✔✔The Reynolds number helps predict flow patterns in different fluid flow situations, indicating
whether the flow is laminar or turbulent based on viscosity, density, and velocity.
How do gears transmit power in machinery?
✔✔Gears transfer power through rotational motion, where the teeth of one gear engage with
another, allowing for speed and torque adjustments in mechanical systems.
What is the significance of the load factor in structural engineering?
