1) Support reaction ($rx^n$) calculation:

Step 1 Consider part (CA)

$BM_c = 0$

enter image description here

$V_A \times 6 - 30 \times 6 \times \frac{6}{2} - H \times 4 = 0$

$6V_A - 4H - 540 = 0$

$V_A = \frac{4H + 540}{6}$ -------- (1)

step 2 part (CB)

$BM_c = 0$

enter image description here

$V_B …
