- A 100 kg block has a coefficient of friction 0.30. Solve for the friction force between A and B.The two sheets of soft plastic are bonded to the central steel strip. Determinethe magnitude of the largest force P that can be safely applied to the steel strip andthe corresponding displacement of the strip. For the plastic, use tw = 10 ksi and G = 800 ksi. Neglect deformation of the steel strip.Axial deformation in a bar loaded in the axial direction can be reduced by which of the following? a.Decreasing the cross-sectional area b.Decreasing the length c.Decreasing the modulus of elasticity d.Increasing the applied load
- Materials can have different masses but equal volumes. a. TRUE b. FALSEPlate with 0.13 m wide and 0.25 m length passes thru oil with layer 3.5 mm and 5 mm thick. Both surface sides of the plate touch the oil that has a viscosity of u=0.038 Ns/m^2. Determine the force required (in newton) to move the plate at speed of 5 mm/sThe brass strip AB has been attached to a fixed support at A and rests on a rough support at B. Knowing that the coefficient of friction is 0.60 between the strip and the support at B, determine the decrease in temperature for which slipping will impend.
