RafaBoth Izod and Charpy tests are used to measure the impact strength of materials, but the main difference lies in the direction of the impact force. The Izod test involves a single impact from a swinging pendulum on a notched specimen, while the Charpy test involves a swinging pendulum striking a notched specimen in a horizontal position. Charpy tests are more common due to their simplicity and reproducibility, but both tests provide valuable information about a material's toughness.

What are the purposes of izod test?
The Izod test is used to evaluate the impact resistance of materials, particularly polymers and composites. It helps determine the amount of energy required to break a notched specimen under a single impact blow. This test is crucial for assessing material toughness and determining if a material is suitable for specific applications.
What is the definition of potential defference?
Potential difference is the difference in electric potential between two points in an electric field. It is measured in volts and represents the work done per unit charge in moving a test charge between the two points.
What does a manometer test relate to?
A manometer test is used to measure the pressure of a gas or liquid in a closed system. It provides information on the pressure difference between two points within the system, helping to assess the efficiency or performance of the system.
In weight test what is the difference between a static test load and a dynamic test load?
A static test load is applied gradually and held constant to measure the structure's deformation and ultimate load-carrying capacity. On the other hand, a dynamic test load is applied rapidly and repeatedly to simulate real-life conditions and assess the structure's response to dynamic loads such as wind or seismic activity.
What is difference between electromyogram and electromyograph?
An electromyogram (EMG) is a test that measures muscle electrical activity, while an electromyograph (EMG) is the instrument used to perform the test. The EMG records electrical signals produced by muscles during contraction and at rest, providing information about muscle function and nerve activity.
