all of them
A mousetrap car uses mechanical energy stored in the spring of the mousetrap. When the trap is released, the spring unwinds, converting the mechanical energy into kinetic energy that propels the car forward.
I use Plastruct for modelling bridges.
To calculate the restoring force according to Hooke's Law, you can use the formula F = -kx, where F is the restoring force, k is the spring constant, and x is the displacement from the equilibrium position. By multiplying the spring constant with the displacement, you can determine the magnitude and direction of the restoring force acting on the object.
yes, most electric violins use normal bridges.
Bridges typically have three characteristics and are built into three different types. These include truss bridges, beam bridges, and suspension bridges.

Certainly some bridges can. Swing bridges, bridges that raise up, these though, stay in one location. Pontoon bridges are capable of being moved from place to place and are in use worldwide.
One of the main types of transportation the Aztecs used was walking. They also had canoes that they would use, and moveable bridges that helped them to travel.
An example of a Hooke's Law problem is calculating the force required to stretch a spring a certain distance. To solve this problem, you can use the formula F kx, where F is the force, k is the spring constant, and x is the distance the spring is stretched. Simply plug in the values for k and x, and solve for F to find the required force.
Due to repeated stress and strain, the material used in the bridges loses elastic strength and ultimately may be collapsed. Hence, bridges are declared unsafe after long use
steel
because they wanted to keep the water from flooding their city and break the bridges
