2. TUMPUAN
TUMPUAN adalah pondasiatau penahan dari semua pekerjaan sipil
yang berfungsiuntuk menahan beban . Tumpuan terbagi atas 3 macam yaitu :
a. Sendi
b. Rol
c. Jepit
a. Sendi atau bisa di sebut engsel ini adalah salah satu daritumpuan, sendi
hanya dapat menerima atau menahan beban yang vertikal (↕) dan beban yang
horizontal(↔) tapi tidak bisa menahan momen .
b. Rol adalah salah satu dari tumpuan, rolhanya dapat menerima atau
menahan beban yang vertikal (↕) tapi tidak bisa menahan beban yang
horizontal(↔) dan momen .
c. Jepit adalah salah stu dari tumpuan yang dapat menerima atau menahan
beban yang vertikal (↕) dan beban yang horizontal(↔) maupun beban
momen .
NOTE : tumpuan sendi bisa menerimabeban vertikal
dan beban horizontal , dan rol hanya bisa menahan
beban vertikal,sedangkan jepit bisa menahan semua
beban termasuk vertikal , horizontal maupun momen
3. Beban
Beban terbagi atas 2 macam yaitu :
a. Beban terpusat
b. Beban terbagi rata/merata
a. Beban terpusat adalah beban yang terpusatpada satu titik (↓)
b. Beban merata adalah beban yang terbagi rata bukan hanya di satu titik
bebannya (↓↓↓↓↓↓)
Dalam MEKANIKA REKAYASAdianjurkan mengikuti ARAH JARUM JAM
Note : momen adalah beban di kali jarak yang
harus membentuk sudut 90o
4. Keterangan :
a. RA = reaksititik (A)
b. RB = reaksititik (B)
c. P1 = beben titik terpusat1
d. P2 = beban titik terpusat2
Aksi = Reaksi
P1 + P2 = RA + RB / P1 + P2 – RA – RB = 0
6. b. Momen
MA = MB = 0
MC = 2RA
= 2(2.5)
= 5 ton meter (tm)
MD = 7RA – 5P1
= 7(2.5) –5(2)
= 17.5 - 10
c. Gaya lintang / Geser
DA = RA = 2.5
DC = RA – P1
= 2.5 – 2
= 0.5 ton (t)
DD = DC – P2
= 0.5 – 3
= -2.5 ton (t)
DB = DD + RB
= -2.5 + 2.5
= 0 ton (t)
9. b. Momen
MA = MB = 0
MC = 1RA MD = 5RA – 4P1
= 1 × 3,49 = 5(3,49) –4(2)
= 3,49 tm = 9,45 tm
ME = 7RA – 6P1 – 2P2
= 7(3,49) –6(2) –2(3)
= 6,43 tm
c. Geser
DA = RA = 3,49
DC = RA – P1 DD = DC – P2 DE = DD – P3y
= 3,49 – 2 = 1,49 –3 = -1,51 – 0,64
= 1,49 t = -1,51 t = -2,15 t
DB = DE + RB
= -2,15 +2,15
= 0 t
d. Gaya normal
Menuju sendi = (-) min, meninggalkan sendi = (+) plus
N = P3x = 0,77 t

11. Overstek
Overstek adalah bagian yang lebih/menempel pada dinding luar dari
sebuah bangunan yang tidak memiliki tompangan (melebihi tempat adanya
tumpuan )
13. b) Momen
MA = MD = 0
MC = 3RA
= 3 . 0,67
= 2,01 tm
MB = 9RA – 6P1
= 3 . 0,67
= 2,01 tm
c) Geser
DA = RA = 0,67 t
DC = RA – P1
= 0,67 – 2
= -1,33 t
DB = DC + RB
= -1,33 + 4,33
= 3 t
DD = DB – P2
= 3 – 3
= 0 t
