The unbalanced wheel has a mass of 15 kg and rolls without slipping on the flat horizontal surface. The wheel has a radius of gy
miv72 [106K]

Answer:

a) a_w=4.331m/s^2

b) F=53.7N

c)\mu=96.5N

Step-by-step explanation:

From the question we are told that

mass of unbalanced wheel M=15kg

Radius of gyration G=64m

Mass center M_c =40mm=4*10^{-2} m

Angular velocity \omega=4rads/s

a)

Generally the equation for moment at point A is mathematically given as

\sum M_a=I \alpha+\sum M \=ad

Where a_w=wheel\ accelaration

15*9.81*(0.04)=0.06144*\frac{a_w}{0.1}+15(0.04)(0.04)\frac{a_w}{0.1}+(15a_w-15(0.04)(4^2)0.1)

5,87=(a_w*0.8544+15a_0-0.96)

a_w=4.331m/s^2

b)

Generally the equation for equilibrium of system on the horizontal axis is mathematically given as

\sum f_x=ma_w

F=ma_w-m \=r w^2

F=(25*4.221)-(15*0.04*4^2)

F=63.3-9.6

F=53.7N

c)

Generally the equation for equilibrium of system on the vertical axis is mathematically given as

\sum f_y=ma_w

Where

F=\mu-mg+m \=r \alpha

\alpha=\frac{a_0}{0.1}

\mu-mg+m \=r \alpha=0

\mu-15*9.81+15*0.04*\frac{4.221}{0.1}

\mu-96.5N=0

\mu=96.5
