The measurement of the attractive forces of mud at rest or under static conditions is known as?

• A. Gel Strength
• B. Viscosity
• C. Density
• D. Plasticity

Answer: (A)

When mud sits still, the particles interact and form a faint, interconnected network. The strength of that network—how much stress is needed to break or deform it while there is no flow—is what gel strength measures. It specifically captures the attractive or cohesive forces holding the mud together in static conditions. Viscosity is about how the mud flows when it’s being sheared, not how stiff it is when at rest. Density only tells you how heavy the mud is per unit volume, and plasticity relates to permanent deformation under load, not the static bonding of the mud’s particles. So gel strength is the measurement of those static attractive forces.
