PROBLEM 10.1: BRAKES A truck has a total weight of 40 kips and is traveling 60 mph. The brake design requires it to stop in 400 ft Assuming that each brake is a disc brake with a mean radius of 10 inches and a friction coefficient of 0.4: 1. Determine the stopping force required. (HINT: Physics and dynamics) 2. Determine the stopping torque required if the wheels are 36 in diameter. (Hint: weight equal for force.) 3. Determine the torque...

*15-8 The automobile has a weight of 2700 lb and is traveling forward at 4 ft/s when it crashes into the wall. If the impact occurs in 0.06s, determine the average impulsive force acting on the car. Assume the brakes are not applied. If the coefficient of kinetic friction between the wheels and the pavement is He 0.3, calculate the impulsive force on the wall if the brakes were applied during the crash. The brakes are applied to all four...

5. Consider the following cart with solid wheels which is attached to a wall by a spring of stiffness k. There are several assumptions that can make this problem more straightforward to solve (it is up to you to decide if these assumptions are reasonable for real life situations): In i. The wheels do not slip while rolling. ii. The center of mass of the entire cart is at point G, at the center of the wheel k-10K ii. The...

The car shown in the figure has mass m(this includes
the mass of the wheels). The wheels have radius r, mass
mw, and moment of inertia
I=kmwr2. Assume that the axles
apply the same torque ? to all four wheels. For
simplicity, also assume that the weight is distributed uniformly so
that all the wheels experience the same normal reaction from the
ground, and so the same frictional force.
Part A
If there is no slipping, a frictional force must...

Rod BC has a weight of 50 N. When θ = 0, the spring is
unstretched. If the weight of the rod causes the spring to stretch
as shown, find the angle the spring makes with the horizon, the
force in the spring, and the stiffness of the spring (K).

this example shows the uses of co-coordinate axes,
my question is why is it that we can substitute T for w2 for
the second equation , won t it be wrong since we are using two
different sets of axes
does it have something to do with expressing newtons second
law in terms of magnittude?
can someone explain more about the uses of co-coordinate axes
and when is it not apprioriate not to use it?

(non calculus based physics) Question 1 An Olympic weight lifter lifts an 1800 N set of weights from the ground to a vertical distance of 2.20 m above his head. Assuming he moves the weights at constant speed, how much work does the weight lifter do? Question 2 A 4.5 kg trunk, initially at rest, takes 2.0 s to slide 2.8 m down a rough 25° slope. Calculate: the work performed by the force of gravity. the amount of mechanical...
