The mass center G of the 16-lbs wheel is off center by 0.70 in. If G is in the position shown as the wheel rolls without slippingthrough the bottom of the circular path of 4-ft radius with a constant angular velocity of 6 rad/sec, compute the normal forceN exerted by the path on the wheel. (Be careful to use the correct mass-center acceleration.)0.7"N =lbs

The hydraulic braking system for the truck and trailer is set to produce equal braking forces for the two units. If the brakes are applied uniformly for 8 seconds to bring the rig (truck and trailer) to a stop from a speed of 32 mi/hr down the 5-percent grade, determine the force P in the coupling between the trailer and the truck. The truck weighs 19,000 lbs and the trailer weighs 15,000 lbs. State whether the coupling is in tension or compression.
Determine the angular velocity 0 in rad/s of the radial line OA at this instant if the truck has a speed of 40.9 ft/s. r = 364 ft
Please answer this NEATLY, COMPLETELY, and CORRECTLY for an UPVOTE. The car has a forward acceleration of a = 4.7 m/s2 without slipping its 630-millimeter diameter tires. Determine (a) the velocity (v) of the car when point P at the tire (corresponding to θ = 43° as shown) has zero horizontal component of acceleration. Also, compute for (b) the total acceleration at point P.NOTE: Use purely RMA Method for velocity and acceleration calculations.
A car having a weight of 40 kN is moving at a certain speed around the curve. Assuming no lateral pressure between the tire and the pavement, compute for the following if the centrifugal ratio is 0.30. (a) Compute the force that will tend to pull the car away from the center of the curve. (b) If the degree of the curve is 4 degrees, determine the maximum speed that the car could move around the curve. (c) Compute for the embankment angle to be provided for this speed if the skid resistance is 0.12.
The radius of a highway curve is 120m, and has an angle of 9.31° from the horizontal. The center of gravity of the car is located 0.80m above the roadway and the distance between the two front wheels is 1.2m. If the car has a total weight of 15KN, a. Determine the normal acceleration and the velocity (in kph) of the car before overturning? b. Find the maximum velocity of the car could move along the curve so that there will be no outstanding pressure between the tires and the roadway. c. If the coefficient of kinetic friction is 0.60, what is the maximum velocity (in kph) of the car without sliding?
QA2- 2-D Motion An unmanned vehicle follows a curved path, beginning at O and ending at A, of length 18 m. At O the speed of the vehicle is 12 m/s and it has slowed to 6 m/s at A. The tangential deceleration of the vehicle is proportional to the distance from O. a) Write an equation for tangential acceleration. b) Find the constant of proportionality in your equation. c) If the resultant acceleration at A is 10 m/s, determine the radius of the curved path at A. Hint: Don't forget that the vehicle has both tangential and centripetal acceleration. In part (c), you should aim to write an expression for the resultant acceleration with radius as the only unknown.
