Engineering Mechanics A block of mass 20 kg lying on a rough horizontal plane is connected by a light string passing over a smooth pulley to another mass 5 kg, which can move freely in the Vertical direction, as shown in the below figure. The tension in the string will ___________ with the increase in coefficient of friction. Decrease Not be effected None of these Increase Decrease Not be effected None of these Increase ANSWER DOWNLOAD EXAMIANS APP
Engineering Mechanics A body of weight 'W' is required to move up on rough inclined plane whose angle of inclination with the horizontal is 'α'. The effort applied parallel to the plane is given by (where μ = tanφ = Coefficient of friction between the plane and the body.) P = W tanα P = W (cosα + μsinα) P = W (sinα + μcosα) P = W tan (α + φ) P = W tanα P = W (cosα + μsinα) P = W (sinα + μcosα) P = W tan (α + φ) ANSWER DOWNLOAD EXAMIANS APP
