Five different water environments were tested: tap water, normal seawater (reference salinity value), seawater with double reference salinity value, seawater with half of the reference salinity and seawater with a quarter of the reference salinity value. Samples of two different adhesive compounds were prepared using the epoxy resin and triethylenetetramine curing agent. One of the compounds was filled with calcium carbonate. The samples were aged in five different water environments for three months, one month and one week, respectively. Mechanical properties of the cured adhesive compound samples were determined via strength tests performed on the Zwick/Roell Z150 testing machine in compliance with the EN ISO 604 standard. The objective of the experiments was to determine the effect of different seawater environments on sel...

Breaks are used to slowdown the moving body or to completely bring the body to the state of rest. Breaks are very important components in an automobile. Electromagnetic braking system makes use of magnetic force to attain breaking. Electromagnets are powered externally using batteries. In our approach ultrasonic sensor is placed in the front of the vehicle. Sensors are used to detect the obstacle and the distance between the vehicle and the obstacle. Microcontroller is used to trigger the electromagnetic braking system if there are any obstacles. This method helps to prevent the accidents caused due negligence of the drivers
