First of all, that will be the situation every time, because if the effort force isn't missing,
then you have have no reason to calculate it.
In order to calculate a missing piece of information, follow these steps:
1). Quit fretting and whining about the information you don't have.
2). Gather the information that you do have.
3). Gather all the equations and formulas you know that relate the information you do have
to the item you're trying to find.
4). Select the best formula and apply it.
If you know the amount of work, and distance, set up an algebraic expression. For instance if the amount of work is 40, and the distance is 2 feet, and you let F= effort force, the equation is 2F=40. You solve by dividing by both sides by 2. So, the effort force is 20.
load force and friction oppose the effort force
The AMA of a machine is calculated using the formula AMA = R / Eactual where R is the resistance force, and Eactual is the actual effort force.
The effort force is the force that is applied to an object that causes it to move. The object reciprocates with a resistance force. If the effort force is greater than the resistance force, the object moves.
the acceleration of the effort force

YOou screw it
no, you cannot calculate effort for effort is not an equation its is just how much force you apply on an object their is no way to show the formula for effort their is no formula for effort no you're wrong you don't even know which there you are suppose to use so how do you know the answer you probally guest.
Whatever output force is required, you can divide it by the "mechanical advantage" to calculate the input force.
torque in * input rpm/output rpm = torque out
load force and friction oppose the effort force
The AMA of a machine is calculated using the formula AMA = R / Eactual where R is the resistance force, and Eactual is the actual effort force.
The effort force is the force that is applied to an object that causes it to move. The object reciprocates with a resistance force. If the effort force is greater than the resistance force, the object moves.
the acceleration of the effort force
Actually, pulleys cannot multiply effort force. It can only change the direction of the effort force.
If by effort you mean the force, (5kg x 9.81m/s²) = 49.05 Newtons. If you mean the amount of work, take the value of force and multiply it by the height in meters. 49.05N x (Height) = work (Joules)
To do this you first have to calculate your ideal mechanical advantage (IMA). The IMA is equal to the effort distance (the distance from the fulcrum to where you will apply the effort) divided by the load distance (the distance from the fulcrum to the load). You can then set your IMA equal to your acutal mechanical advatage (AMA) which assumes 100% efficiency. The AMA is equal to the load force (the weight of what you are lifting) divided by the effort force (the # you are looking for). So, for example, if your IMA is 5 and your load force is 500 lbs: 5=500/effort force. Therefore the effort force would be 100 pounds.
