The brake pads for a bicycle tire are made of rubber. If a frictional force of 50 N is applied to each side of the tires, determ
1 answer:
Answer:
average shear strain in the rubber is 0.25rad
Explanation:
The base has a dimension of 20mm and 50mm.
frictional force is 50 N
using the expressed shear stress,
we will determine τ =
τ = 50 / 1000
= 0.05MPa
shear stress τ = γ .G
τ = shear stress
γ = shear strain
G = 0.20MPa
γ = τ / G
= 0.05 / 0.20
= 0.25rad
average shear strain in the rubber is 0.25rad

Answer:
The voltage across the capacitor is 1.57 V.
Explanation:
Given that,
Number of turns = 10
Diameter = 1.0 cm
Resistance = 0.50 Ω
Capacitor = 1.0μ F
Magnetic field = 1.0 mT
We need to calculate the flux
Using formula of flux
Put the value into the formula
We need to calculate the induced emf
Using formula of induced emf
Put the value into the formula
Put the value of emf from ohm's law
We know that,
We need to calculate the voltage across the capacitor
Using formula of charge
Put the value into the formula
Hence, The voltage across the capacitor is 1.57 V.
