Abstract

"MEDIçãO DE VELOCIDADE DE PRANCHA DE SURF POR EXTENSÈMETROS". é um dispositivo para medir a velocidade de uma prancha de surf ou similar em relação à água utilizando o princípio da medição de deformações por extensómetros; o dispositivo é composto por uma haste (3) a qual tem uma de suas extremidades fixada na prancha (1) e a outra extremidade, livre, contém uma esfera (4), de modo que com a movimentação da prancha (1), a força da água sobre a esfera (4) faz com que a haste (3) se deforme, por flexão e a deformação é medida por extensómetros (5) e posteriormente processada para obtenção dos valores da velocidade relativa."SURF BOARD SPEED MEASUREMENT BY EXTENSORS". is a device for measuring the speed of a surfboard or the like relative to water using the strain gauge measurement principle; the device is composed of a rod (3) which has one end fixed to the board (1) and the other free end contains a ball (4), so that with the movement of the board (1), the The force of water on the ball (4) causes the rod (3) to deform by flexion and the strain is measured by strain gauges (5) and further processed to obtain relative velocity values.
