For example, a rough piece of wood would have a higher coefficient of static friction than a smooth piece of metal.ДЄs shown in Figure 2, the only forces acting on m 2В are the force due to gravity and the tension from the string. The magnitude of static friction depends on the material used and what is called, вЂњthe coefficient of static frictionвЂќ. This is done by adding masses to the mass hanger. This force must be overcome before the block will slide up the ramp. Static friction is a force that tries to keep the object static, or motionless. The last force acting on the block is static friction, f s. It is directed along the direction of the rope and away from the object Tension, T, is the force exerted on the block by the string. However, since the object is inclined to the plane of the table, there will be components of the force of gravity in both the xВ and yВ directions.ДЄnother force acting on m 1В is the normal force which is the force exerted by the ramp onto the block to compensate for the force of gravity pulling the block downwards. This force is essentially the вЂweightвЂ™ of the object: Fg = mgВ where mВ is the mass of the object and gВ is the acceleration due to gravity (9.8 m/s 2). To begin, each mass is acted upon by gravity, which acts straight down.

It is important to take note of the chosen directions of xВ and yВ in each of the free body diagrams вЂ“ this is arbitrary and can be put in any direction that makes analysis easiest (note that in the case of m 1В the xВ direction was chosen to be parallel to the face of the ramp so that the tension and normal forces are directly along each of the directions.) Many different types of forces are present in this demonstration. A free body diagram for each mass is shown in Figure 2.ДЇigure 2: Left: mass hanger m 2 Right: block m 1 The mass can usually be simplified to a dot representing the objectвЂ™s center of mass, and the forces are then vectors extending out from the dot in the direction they are applied. See Figure 1 for a diagram of the demo set up.ДЇree body diagrams show all of the forces acting on each individual mass in a system. In this demonstration, a wood block is pulled up an inclined plane by masses hanging from a pulley attached to the ramp. The forces can then be analyzed easily using NewtonвЂ™s second law of motion. One of the earliest diagrams that are used in this method illustrate forces.Free body diagrams are a great way to simplify a complicated situation involving many different types and directions of forces. ItвЂ™s impossible to get a clear picture of your customersвЂ™ Jobs to Be Done without analyzing the mountain information you collect and presenting it visually.

What characteristics they use to compare solutions.

How they found out about the solutions they purchase.

The circumstances that pushed them to look for and purchase a solution.

The fears that hold them back from switching solutions.

The emotional reasons that drive them to purchase one solution and avoid another.

You will collect a lot of information from your customers as you follow the JtBD method: The Jobs to Be Done method lets you dig deep in your customer interviews to find the true, underlying motivations for why they purchase the solutions they do.

But these answers lead to misdirected or inappropriate products and services (solutions).

It is easy to get shallow and non-detailed answers and statistics when you directly ask your customers вЂњWhat do you want?вЂќ, вЂњWhy do you want it?вЂќ, and вЂњWhich product do you prefer?вЂќ. ItвЂ™s more than just a straightforward task, itвЂ™s also includes the situation and the experience the customer wants to have. вЂњJobвЂќ is shorthand for the goal that a customer wants to achieve.
