Support Force Calculator:
Enter the values of masses of the objects, M1(kg) and M2(kg) and acceleration due to gravity, a(m/s2) to determine the value of support force, SF(N).
Support Force Formula:
Support force refers to the force that a support structure must exert to hold up objects against the force of gravity.
Support force, SF(N) in Newtons is equated by the product of sum of masses of the objects, M1(kg) and M2(kg) in kilograms and acceleration due to gravity, a(m/s2) in metres per second squared.
Support force, SF(N) = (M1(kg) + M2(kg)) * a(m/s2)
SF(N) = support force in Newtons, N.
M1(kg) + M2(kg) = masses of the objects in kilograms, kg.
a(m/s2) = acceleration due to gravity in metres per second squared, m/s2, approximately 9.81m/s2 on the surface of the Earth.
Support Force Calculation:
- Calculate the support force required to hold up two objects with masses of 10 kg and 15 kg, respectively.
Given: M1(kg) = 10kg, M2(kg) = 15kg.
Support force, SF(N) = (M1(kg) + M2(kg)) * a(m/s2)
SF(N) = ( 10 + 15 ) * 9.81
SF(N) = 245.25N.
- Assume you have a support force of 196.2 Newtons, the mass of the second object is 10 kg, and the acceleration due to gravity is 9.81m/s2. Find M1(kg).
Given: SF(N) = 196.2N, M2(kg) = 10kg.
Support force, SF(N) = (M1(kg) + M2(kg)) * a(m/s2)
M1(kg) = ( SF(N) / a(m/s2) ) – M2(kg)
M1(kg) = (196.2 / 9.81) – 10
M1(kg) = 20 – 10
M1(kg) = 10kg.
