## Calculation

### Vertical end reactions $R_A$

$$R_A=\cfrac{12\cdot E\cdot I\cdot Δ_o}{l^3}$$

### Reaction end moment $M_A$

$$M_A=\cfrac{-6\cdot E\cdot I\cdot Δ_o}{l^2}$$

### Angular displacement $θ_A$

$$θ_A=0$$

### Deflection $y_A$

$$y_A=0$$

### Vertical end reactions $R_B$

$$R_B=-R_A$$

### Reaction end moment $M_B$

$$M_B=-M_A$$

### Angular displacement $θ_B$

$$θ_B=0$$

### Deflection $y_B$

$$y_B=0$$

### Max. moment +

$$M_{max+}=M_B$$

### Max. moment -

$$M_{max-}=M_A$$

### Max. angular displacement

$$θ_{max}=\cfrac{-3\cdot Δ_o}{2\cdot l}$$

### Max. deflection +

$$y_{max+}=\cfrac{Δ_o}{l^3}\cdot\left(l^3+2\cdot a^3-3\cdot a^2\cdot l\right)$$

### Max. deflection -

$$y_{max-}=\cfrac{-Δ_o\cdot a^2}{l^3}\cdot\left(3\cdot l-2\cdot a\right)$$

### Transverse shear

$$V=R_A$$

### Bending moment

$$M=M_A+R_A\cdot x$$

### Slope

$$θ=θ_A+\cfrac{M_A\cdot x}{E\cdot I}+\cfrac{R_A\cdot x^2}{2\cdot E\cdot I}$$

### Deflection

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