PAE(01/13/25): Statics Principles

What is the study of forces in equilibrium called?

• Dynamics

• Kinetics

• Statics

• Thermodynamics

What does equilibrium mean in the context of statics?

• The sum of all forces and moments equals zero

• The object is moving at a constant speed

• The object is accelerating

• The forces are unbalanced

Why is understanding statics important for engineers?

• To design structures that can withstand forces without collapsing

• To increase the speed of vehicles

• To improve the efficiency of engines

• To reduce the weight of materials

In the context of the provided diagram, what condition must be met for the seesaw to be in equilibrium?

• Different weights on each side

• Equal weights at different distances

• Equal weights at equal distances

• No weights on the seesaw

What is a real-life example of forces in equilibrium?
