static friction between the tires and the road is
μs = 0.2 . Determine the maximum constant speed
at which the car can travel without sliding up the slope. Neglect
the size of the car.

I understand how to do it, but am not sure how to get the angle
(from the positive x axis) that the normal forces and friction
forces are for the FBD.
The car has a mass of 1.6 Mg and center of mass at G. If the coefficient of static friction between the shoulder of the road and the tires is丛= 0.42, determine the greatest slope θ the shoulder can have without causing the car to slip or tip over...

QUESTION 5 [4 marks for (a) and (c); 2 marks for (b)] (a) Consider a block of weight W resting on a board of variable inclination angle e. Draw the free body diagram for the block under the following different conditions, also including the horizontal and vertical components of the force vectors and the relationship between the angle of inclination and angle of static friction: i no friction, ii no motion, motion impending, and iv....
A woman climbs a ladder against the side of the building and wants to climb 3/4 of the way to the end of the ladder. What is the minimum coefficient of friction needed to keep the ladder from sliding out from under her? The mass of the ladder is 11.6 kg, and its length is 8.95 m, the mass of the woman is 36.5 kg, and the ladder makes an angle of 0 =57.6º do the ground as is shown...
1. The figure shows a box with mass m1 on a
frictionless plane inclined at angle ?1. The
box is
connected via a cord of negligible mass to another
box with mass m2 on a frictionless plane
inclined at
angle ?2 (> ?1). The pulley
is frictionless and has
negligible mass and assumes that the setup is on the
surface of the earth.
a) Provide free-body force diagram for both boxes.
b) What is the acceleration in terms of m1,...
A student is riding their bike when they come across a turn in the form of a circular arc of radius R 3.0m as pictured in the diagram below and travel along this arc in the clockwise direction. At one point along this trajectory (the origin of the given coordinate system) it makes sense to define the Cartesian coordinate system shown where the x-axis is tangent to the trajectory and the y-axis is perpendicular to it. At this point the...
Problem A car travels at a constant speed of 29.5 mi/h (13.2 m/s) on a level circular turn of radius 46.0 m, as shown in the bird's-eye view in Figure 7.13a. What minimum coefficient of static friction, Aus, between the tires and the roadway will allow the car to make the circular turn without sliding? Strategy In the car's free-body diagram (Fig. 7.13b) the normal direction is vertical and the tangential direction is into the page (step 2). Use Newton's...
