Two different options A and B with brake pads for disc brakes are connected to the rope drum. The diameter of the rope drum is 150 mm. What distance must the pads B be at from the center of rotation to cover the same distance as A?A B- Width 50 mm - Width 60 mm- Evidence center 120mm - Construction power 900 N from rotation center.- Maintains a weight of 200 kgwhen the installation force is 1.4kN
(μ is missing from the data)M=μF(Ry-Ri)Right answer R=187 mm
Assume the xy plane is level ground, and that the vertical pole shown in the diagram lies along the z-axis with its base at the origin. If the pole is 5 m tall, and a rope is used to pull on the top of the pole with a force of 400 N as shown, determine the magnitudes of the parallel and perpendicular components of the force vector with respect to the axis of the post i.e. with respect to the z-axis.
