The present study includes the investigation on the frictional dynamics of hard and soft solid interface using low velocity linear tribometer. The effects of gelatin concentration, nanoparticles concentration, normal stress, and sliding velocity on the static and dynamic frictional shear stresses acting on the sliding gel block are studied using response surface methodology (RSM). The shear sliding experiments are conducted in steady sliding regime, well above the critical velocity. L31 orthogonal array consisting of five levels for each factor is selected for the experimentation and second-order quadratic model has been generated for both the responses. The mathematic models are validated with the available trends mentioned in the literature.
