Hello students in this question given as a length of the rod is 150 mm diameter is 20 mm. Poisso

We have given two long barrage and both are moving the same direction in still water and we have

First we will calculate the lateral strain in the brass road can be given by the change in the l

Here from this diagram, we have the rod with sleeve showing the applied force, and here F is the

hi this is a question based on elasticity so here we have v naught is equal to it is delta R by

Question

A tensile flap has a resistance of 150 ohms at rest, an effective length of 120 millimeters, and a 'Gauge factor' equal to 2.1. The tension flap is mounted on a load cell, which means that the tension flap is stretched or compressed with an effective length change of 2.5 millimeters at a maximum load of 500 kg. Four such tension flaps are connected to a measuring bridge (full bridge), which is supplied with 12 V DC. Two of the tension flaps are compressed, and the other two are stretched. The compression and stretching are equal. a) What is the resistance of the tension flaps that are stretched and the tension flaps that are compressed at maximum load? b) What voltage does the measuring bridge emit at maximum load? c) What voltage does the measuring bridge emit at a load of 1 kg? d) Discuss qualitatively how good the measurement made in c) will be.
