## Values for calculation

$E$ $\mathrm{MPa}$
$I$ $\mathrm{mm^4}$
$x$ $\mathrm{mm}$

## Calculation

### Vertical end reactions $R_A$

$$R_A=0$$

### Reaction end moment $M_A$

$$M_A=W\cdot\left(l-a\right)$$

### Angular displacement $θ_A$

$$θ_A=0$$

### Deflection $y_A$

$$y_A=\cfrac{-W\cdot\left(l-a\right)}{6\cdot E\cdot I}\cdot\left(2\cdot l^2+2\cdot a\cdot l-a^2\right)$$

### Vertical end reactions $R_B$

$$R_B=W$$

### Reaction end moment $M_B$

$$M_B=0$$

### Angular displacement $θ_B$

$$θ_B=\cfrac{W}{2\cdot E\cdot I}\cdot\left(l^2-a^2\right)$$

### Deflection $y_B$

$$y_B=0$$

### Max. moment

$$M_{max}=M_A$$

### Max. angular displacement

$$θ_{max}=θ_B$$

### Max. deflection

$$y_{max}=y_A$$

### Transverse shear

$\text{if }\ x\le a$
$$V=R_A$$
$\text{else}$
$$V=R_A-W$$

### Bending moment

$\text{if }\ x\le a$
$$M=M_A+R_A\cdot x$$
$\text{else}$
$$M=M_A+R_A\cdot x-W\cdot\left(x-a\right)$$

### Slope

$\text{if }\ x\le a$
$$θ=θ_A+\cfrac{M_A\cdot x}{E\cdot I}+\cfrac{R_A\cdot x^2}{2\cdot E\cdot I}$$
$\text{else}$
$$θ=θ_A+\cfrac{M_A\cdot x}{E\cdot I}+\cfrac{R_A\cdot x^2}{2\cdot E\cdot I}-\cfrac{W}{2\cdot E\cdot I}\cdot\left(x-a\right)^2$$

### Deflection

$\text{if }\ x\le a$
$$y=y_A+θ_A\cdot x+\cfrac{M_A\cdot x^2}{2\cdot E\cdot I}+\cfrac{R_A\cdot x^3}{6\cdot E\cdot I}$$
$\text{else}$
$$y=y_A+θ_A\cdot x+\cfrac{M_A\cdot x^2}{2\cdot E\cdot I}+\cfrac{R_A\cdot x^3}{6\cdot E\cdot I}-\cfrac{W}{6\cdot E\cdot I}\cdot\left(x-a\right)^3$$
