You probably think of wet surfaces as being slippery. Surprisingly, the opposite is true for human skin, as you can demonstrate by sliding a dry versus a slightly damp fingertip along a smooth surface such as a desktop. Researchers have found that the static coefficient of friction between dry skin and steel is 0.27, while that between damp. skin and steel can be as high as 1.4. Suppose a man holds a steel rod vertically in his hand, exerting a 400 N grip force on the rod. What is the heaviest rod he can hold without slipping if his hands are dry? Express your answer with the appropriate units. mary HA Value Part B m Submit Previous Answers Request Answer * Incorrect; Try Again; 3 attempts remaining Enter your answer using units of mass.
