Berikut adalah video penjelasan untuk case 1 yang ada pada UTS

Cara 1

from math import *

g = 9.81
m1 = int(input("Massa 1: "))
m2 = int(input("Massa 2: "))
m3 = int(input("Massa 3: "))
u_1 = eval(input("u1: "))
u_2 = eval(input("u2: "))
u_3 = eval(input("u3: "))
alpha = eval(input("sudut alpha: "))
a = eval(input("percepatan: "))
c = sin (alpha)
d = cos (alpha)

t1 = m1*g*(c-u_1*d) - m1*a
t2 = m2*g*(c-u_2*d) + t1 - m2*a
t3 = m3*g*(c-u_3*d) + t2 - m3*a

print("tegangan total: ",t3)

Cara 2

Algoritma 2

from numpy import *

g = 9.81 #percepatan gravitasi
m1 = eval(input("Massa 1: ")) #untuk menginput nilai m1
m2 = eval(input("Massa 2: "))
m3 = eval(input("Massa 3: "))
u_1 = eval(input("Koef gesek 1: "))
u_2 = eval(input("Koef gesek 2: "))
u_3 = eval(input("Koef gesek 3: "))
a = eval(input("percepatan: ")) #percepatan yang ada dibidang miring
sudutalpha = eval(input("alpha: "))
alpha = (sudutalpha * 1/180)*pi
c = sin(alpha)
d = cos(alpha)

b1 = m1*g*(c-u_1*d) - m1*a
b2 = m2*g*(c-u_2*d) - m2*a
b3 = m3*g*(c-u_3*d) - m3*a

b = array([b1,b2,b3])
T = array([[1,0,0],
          [-1,1,0],
          [0,-1,1]])

hasil = linalg.solve(T,b)
T1 = hasil[0]
T2 = hasil[1]
T3 = hasil[2]

print(f'Tegangan tali= {T3}')

Berikut adalah video penjelasan untuk case 2 yang ada pada UTS

from math import *
from sympy import *

g  = 9.81
rho = 1.2

cd = float(input("drag coefficient: "))
area = float(input("luas area: "))
v1 = float(input("kecepatan akhir: "))
m = float(input("massa mobil(kg): "))
u = float(input("koef gesek: "))
e = float(input("percepatan: "))

fg = m*g*u
fmobil = m*e

for vo in range (0,v1):
  fdrg = (cd*area*rho*vo**2)/2
atot = (fmobil - (fdrg+fg))/m
t1 = - v1/atot

print("percepatan tot: ", atot)
print("waktu t1: ", t1)
