The brake pads for a bicycle tire are made of rubber.

If a frictional force of 50 N is applied to each side of the tires, determine the average shear strain in the rubber. Each pad has cross-sectional dimensions of 20 mm and 50 mm.

${G}_{r}=0.20MPa$

The base is 20 mm and 50 mm in size. The strain in the tire must be ascertained.Friction force

Using the expressed shear stress, we will determine T.

Surface cross-sectional area:

We can also calculate the shear stress in the following way.

Where:

The solution is:

Given that $\Rightarrow$ Area of cross section $\left(Acs\right)=50\times 20$

$\Rightarrow Acs=1000m{m}^{2}$

Forse$\left(F\right)=50N$ , $G=0\cdot 2MPa$

$\because ShearstressPSK\left(\tau \right)=\frac{F}{Acs}=\frac{50}{1000}=0.05MPa$

As we know$\Rightarrow Shearstra\in =\frac{Shearstress}{Shear\text{mod}\underset{\u2015}{e}s}$

$\Rightarrow \gamma =\frac{\tau}{4}$

$\Rightarrow \gamma =\frac{0.05}{0.2}=0.25rad$
