## Calculation

### Vertical end reactions $R_A$

$$R_A=0$$

### Reaction end moment $M_A$

$$M_A=0$$

### Angular displacement $θ_A$

$$θ_A=\cfrac{-γ}{2\cdot t\cdot l}\cdot\left(T_2-T_1\right)\cdot\left(l-a\right)^2$$

### Deflection $y_A$

$$y_A=0$$

### Vertical end reactions $R_B$

$$R_B=0$$

### Reaction end moment $M_B$

$$M_B=0$$

### Angular displacement $θ_B$

$$θ_B=\cfrac{γ}{2\cdot t\cdot l}\cdot\left(T_2-T_1\right)\cdot\left(l^2-a^2\right)$$

### Deflection $y_B$

$$y_B=0$$

### Max. moment

$$M_{max}=0$$

### Max. angular displacement +

$$θ_{max+}=θ_B$$

### Max. angular displacement -

$$θ_{max-}=θ_A$$

### Max. deflection

$$y_{max}=\cfrac{-γ}{8\cdot t\cdot l^2}\cdot\left(T_2-T_1\right)\cdot\left(l^2-a^2\right)^2$$

### Transverse shear

$$V=R_A$$

### Bending moment

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

### Slope

$\text{if }\ x\le a$
$$θ=θ_A+\cfrac{M_A\cdot x}{E\cdot I}+\cfrac{R_A\cdot x^2}{2\cdot E\cdot I}$$
$\text{else}$
$$θ=θ_A+\cfrac{M_A\cdot x}{E\cdot I}+\cfrac{R_A\cdot x^2}{2\cdot E\cdot I}+\cfrac{γ}{t}\cdot\left(T_2-T_1\right)\cdot\left(x-a\right)$$

### Deflection

$\text{if }\ x\le a$
$$y=y_A+θ_A\cdot x+\cfrac{M_A\cdot x^2}{2\cdot E\cdot I}+\cfrac{R_A\cdot x^3}{6\cdot E\cdot I}$$
$\text{else}$
$$y=y_A+θ_A\cdot x+\cfrac{M_A\cdot x^2}{2\cdot E\cdot I}+\cfrac{R_A\cdot x^3}{6\cdot E\cdot I}+\cfrac{γ}{2\cdot t}\cdot\left(T_2-T_1\right)\cdot\left(x-a\right)^2$$
