A ductile cast-iron bar is to support a load of 178 kN in a heat-treating furnace used to make malleable cast iron. The bar is l
ocated in a spot that is continuously exposed to 500°C. Design the bar so that it can operate for at least 10 years without failing.

Answer:
T = T
Explanation:
The period of a simple pendulum is given by the formula
Where
l - length of the pendulum
g - acceleration due to gravity
The dimension of the physical quantities are given by,
t - T
l - L
g - m/s² - LT⁻²
Substituting in the above equation,
T = 2π √(L / LT⁻²)
Considering only the dimensional units in the equation
T = √(L / LT⁻²)
T = T
This shows that the formula for a simple pendulum is dimensionally consistent, T = T
