I just need to see a diagram of what problem 3 would look like.
a Dashboard 曲 Events E My Courses This course TWo pulleys of radius 290 Tmm and 190 mm are mounted in an open-belt drive arrangement on two parallel shafts. The pulleys center lines are 0.58 m apart. of 15 stion The big pulley is rotating at 98 rpm and the coefficient of friction between the belt and the pulleys is 0.25 and the tensile force allowed in the belt is 1.2kN. Analyze the belt drive system and calculate: The contact angle at the big pulley: Opig ° (1) The contact angle at the small pulley: 0sm rad ° (2) STm The length of the belt, assuming a negligible thickness: т (3) The torque at the big pulley: Nm, and (1) The torque at the small pulley: Nm (1) The maximum power transmitted through the belt drive system kW (1) If the total mass of the belt is 2.3 kg, assuming a firm grip between pulleys and the belt and the same speed, all other relevant parameters remaining the same as in the statement above, you are required to revisit your analysis with respect to the centrifugal…
Please answer and show how you got it You are on an elevator fixed to a wall that can move up and down freely while you pull with a force of 150 N on a massless rope (the orange line in the diagram below) with length L. This rope is connected to one end of a beam with the same length, L, and mass m=20 kg. The left end of the beam is in contact with the same wall the elevator is on and the coefficient of static friction =0.2 between the beam and the wall. See diagram below for a representation of the situation and note that free fall acceleration points directly downward 0 L Part A) Label all the forces acting on the beam and discuss the direction of any torques exerted on the beam about the contact point between the beam and the wall Part B) What is the maximum angle the beam can subtend with respect to the horizontal _m such that it will just begin to slip? Potentially useful trig identities are sin(2x)=2sin(x)cos, sin(180-x)=sin(x), sin(90+x)=cos(x)

Crate coef of static friction is .55, what is min force to prevent slipping, what is min force to prevent tipping
A steel tire, 20 mm thick, 90 mm wide, and 1600.0 mm inside diameter is heated and shrunk onto a steel wheel 1600.5 mm in diameter. If the coefficient of static friction is 0.40, what torque is required to twist the tire relative to the wheel? Neglect the deformation of the wheel. Use E = 100 GPa.
